The factors of 5 are 1 and 5.
The factors of 10 are 1, 2, 5, and 10.
The factors of 20 are 1, 2, 4, 5, 10, and 20.
The common factors are 1 and 5. Therefore, the least (smallest) common factor is 1.
The factors of 20 are 1, 2, 4, 5, 10, and 20. The factors of 50 are 1, 2, 5, 10, 25, and 50. The common factors of 20 and 50 are 1, 2, 5, and 10. Therefore, the least common factor (the smallest common factor) is 1.
The least common factor is 1. (The least common factor of any two or more positive integers is always 1.)
25 is not a multiple of 10, so the greatest common factor would not be 10. A lower common factor would be 5, because 10, 20 and 25 all divide by 5, so 5 is the greatest common factor of 10, 20 and 25.
The greatest common factor (GCF) of 20 and 30 is 10.
The Least Common Multiple (LCM) of 4, 10, and 20 is 20.
The least common factor of any set of integers is 1.
The least common factor of any set of positive integers is 1.
It is: 1
The least common factor of any set of numbers is 1.
The factors of 20 are 1, 2, 4, 5, 10, and 20. The factors of 50 are 1, 2, 5, 10, 25, and 50. The common factors of 20 and 50 are 1, 2, 5, and 10. Therefore, the least common factor (the smallest common factor) is 1.
They are: 10 and 100 respectively
The greatest common factor of 20 and 120 is 20, and the least common multiple of 20 and 120 is 120
The least common factor is: 1
the least common factor is 1
The least common factor is 1 but the highest common factor is 4
The least common factor of 10 and 25 is: 1. The HIGHEST common factor is 5, and the least common MULTIPLE is 50.
Since 10 is a factor of 20, all of its factors are common.
