Answer: 1
The factors of 9 are 1, 3, and 9.
The factors of 21 are 1, 3, 7, and 21.
The common factors are 1 and 3; the least (smallest) common factor is 1.
The factors of 18 are 1, 2, 3, 6, 9, and 18. The factors of 21 are 1, 3, 7, and 21. The common factors are 1 and 3. Therefore, the least common factor (the smallest common factor) is 1. Factorizations: 18-3x3x2 21-7x3
The least common factor is: 1
The least common factor is: 1
The least common factor of two numbers is always one The greatest common factor of 36 and 45 is 9
The least common factor of any set of positive integers is 1.
The least common factor of 4 and 9 is is: 1
They are 1 and 3 .Note: Those are also the least common factors of 9, 21, and 54 .
The factors of 18 are 1, 2, 3, 6, 9, and 18. The factors of 21 are 1, 3, 7, and 21. The common factors are 1 and 3. Therefore, the least common factor (the smallest common factor) is 1. Factorizations: 18-3x3x2 21-7x3
the least common factor and only common factor of 9, 36, and 64 is 1.
The Greatest Common Factor of 9, 18, 21: 3
The Greatest Common Factor of 60, 21, 9: 3
The least common factor of any set of numbers is 1.
1 but one doesn't count so it would have to be 3
The least common factor of 9, 12 and 18 is 1.
The Greatest Common Factor of 21, 9 is 3.
The least common factor is: 1
21 = 7 x 3 , 9 = 3 x 3 ; for the Least Common Multiple (LCM), 21 already is a multiple of 7. 21 & 9 have a common factor of 3, so LCM = 21 x 3 = 63
