A number is divisible by 3, if the sum of its all digits is a multiple of 3 or divisibility by 3. Consider the following numbers to find whether the numbers are divisible or not divisible by 3: (i) 54. Sum of all the digits of 54 = 5 + 4 = 9, which is divisible by 3.

Here ur answer, Option( a) 123 is divisible by 3 but not by 6…….

The numbers that 87 is divisible by are 1, 3, 29, and 87. You may also be interested to know that all the numbers that 87 is divisible by are also known as the factors of 87.

Since 97 cannot be divided evenly by 2, 3, 5, or 7, we know that 97 is a prime number.

Since 73 cannot be divided evenly by 2, 3, 5, or 7, we know that 73 is a prime number.

Factors of 97 are the numbers which when multiplied in pairs give the product as 97. Like all prime numbers, the only factors of 97 are 1 and 97 itself. Factors of 97 can be positive and negative as well.

The division shows that the number 91 is exactly divisible by 1, 7, 13, and 91.

Solution: By implementing the divisibility rule of 13, we get, 2197: 21 x 4 – 97 = 97 – 84 = 13, and number 13 is divisible by 13, giving the result as 0. Divisibility Rule 4: Multiply the last digit by 9 of a number N and subtract it from the rest of the number.

The numbers that 119 is divisible by are 1, 7, 17, and 119. Not only that, but all the numbers that are divisible by 119 are the divisors of 119.

119 (one hundred [and] nineteen) is the natural number following 118 and preceding 120.

Factors of 119

• Factors of 119: 1, 7, 17, and 119.
• Prime Factorization of 119 : 119 = 7 × 17.

What numbers is 17 divisible by? Is 17 a prime number? 17 is prime! It has no positive factors other than 1 and itself.

Is 17 a perfect square number? A number is a perfect square (or a square number) if its square root is an integer; that is to say, it is the product of an integer with itself. Here, the square root of 17 is about 4.123. Thus, the square root of 17 is not an integer, and therefore 17 is not a square number.

Yes, 17 is a prime number because it only has two factors, 1 and 17. No, 51 is NOT a prime number because it has more than two factors. 51 is a composite number and can be factored by any of the following numbers: 1, 3, 17, 51.

The numbers that 16 is divisible by are 1, 2, 4, 8, and 16. You may also be interested to know that all the numbers that 16 is divisible by are also known as the factors of 16. Not only that, but all the numbers that are divisible by 16 are the divisors of 16.

The numbers that 29 is divisible by are 1 and 29. You may also be interested to know that all the numbers that 29 is divisible by are also known as the factors of 29. Not only that, but all the numbers that are divisible by 29 are the divisors of 29.

A number is divisible by 16 if number formed by last four digits of it is divisible by 16. Illustration: For example, let us consider 769616 Number formed by last four digits = 9616 Since 9522 is divisible by 16, answer is YES. How does this work?

If the sum of the digits of the number are a multiple of 3, then the number is a multiple of 3. Here are some examples: 1113, 117, 18, 37035 are all multiples of 3. If you can DIVIDE it by 3 then it has to be a MULTIPLE of 3 .

The factors of 16 are 1, 2, 4, 8, 16.

Rule: A number is divisible by 4 if the number’s last two digits are divisible by 4. 9,312, for instance, is divisible by 4 since its last 2 digits are 12. And 12 is divisible by 4. Since the last two digits, 12, are divisible by 4, the number 112 is also divisible by 4.

Method 1 (Repeatedly subtract 5 from n) Run a loop and subtract 5 from n in the loop while n is greater than 0. After the loop terminates, check whether n is 0. If n becomes 0 then n is multiple of 5, otherwise not.

The multiples of 12 are 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144,… The multiples of 16 are 16, 32, 48, 64, 80, 96, 112, 128, 144, 160,…
