The least common multiple of 8 and 12 is 24.

To find the exponent form of numbers let’s say 32. Write the product form of 32. 32= 2 x 2 x 2 x 2 x 2= 25. Here 2 is multiplied by 5 times with itself.

Least common multiple (LCM) of 9 and 12 is 36.

2 Answers By Expert Tutors Your second question asks for the LCD for denominators of 9 and 7. A common denominator can always be the product of the two denominators, so 9*7 = 63 is a common denominator. Since one of the denominators is prime, there is no lower common denominator, so the answer is 63.

(8 + 9) = 17 so all you need is your 17 times table: 17, 34, 51, 68… (8 x 9) = 72 so all you need is your 72 times table (which I’m sure you can just rattle off!) : 72, 144, 216, 288…

multiples of 8 ⇒8,16,24,32,40,48,56,64,72…. so the lcm, I.e. least common multiple of 7 and 8 is, 56.

If you’re talking in terms of whole numbers, the number 7 can only go into 8 once.

Answer: LCM of 7 and 8 is 56.

Thus, the factors of 8 are 1, 2, 4 and 8. Factors of 8: 1, 2, 4, and 8.

so, factors of 8 are 1,2,4 and 8. Here one can see easily from all the four factors of 8 ,2,4,8 are even but 1 is odd.

The common factors are 1, 2, 4, and 8. The largest factor for both numbers have in common is 8, so GCF(16,24) = 8.
