What is the least common factor of 15 and 32?

Answer 1

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

The factors of 15 are 1, 3, 5, and 15.

The only common factor is 1. Therefore, the least (smallest) common factor is 1, as is the greatest (largest) common factor.

Answer 2

The least common factor is a term often mistakenly given to either the greatest common factor (GCF) or the least common multiple (LCM). This term is not often used because it does not describe a useful relationship between numbers. Since 1 evenly divides all integers, 1 is technically the least common factor for any set of integers.

15 and 32 are relatively prime, which means that they share no factors aside from 1.

Answer 3

The least common factor is a term often mistakenly given to either the greatest common factor (GCF) or the least common multiple (LCM). This term is not often used because it does not describe a useful relationship between numbers. Since 1 evenly divides all integers, 1 is technically the least common factor for any set of integers.

32 and 45 are relatively prime, which means that they share no factors aside from 1.
The LCF is 1.

The GCF is 1.

The LCM is 1440.

Answer 4

The least common factor of any set of numbers is 1.

Answer 5

The least common factor of any set of non-zero integers is always 1.

Answer 6

The Greatest Common Factor (GCF) is: 1
