Calculator Use For two integers a and b, denoted LCM(a,b), the LCM is the smallest positive integer that is evenly divisible by both a and b. For example, LCM(2,3) = 6 and LCM(6,10) = 30. The LCM of two or more numbers is the smallest number that is evenly divisible by all numbers in the set.

Answer Expert Verified LCM stands for Least Common Multiple while GCF stands for Greatest Common Factor. Given any two numbers, LCM of the numbers is greater than the GCF of the numbers. Because LCM multiplies all the multiples of both numbers while GCF multiples only the factors found in both numbers.

The Greatest Common Factor (also known as GCF) is the largest number that divides evenly into each number in a given set of numbers. The Least Common Multiple (also known as LCM) is the smallest positive multiple that is common to two or more numbers.

Answer: The GCF of 20 and 50 is 10.

5

54 = 2 * 3 * 9, and 45 = 5 * 9. The greatest common is 9.

We found the factors and prime factorization of 32 and 60. The biggest common factor number is the GCF number. So the greatest common factor 32 and 60 is 4.

16

The common factors of 32 and 96 are 32, 16, 8, 4, 2, 1, intersecting the two sets above. In the intersection factors of 32 ∩ factors of 96 the greatest element is 32. Therefore, the greatest common factor of 32 and 96 is 32.

The biggest common factor number is the GCF number. So the greatest common factor 60 and 75 is 15.
