The least common factor is: 1
As 4 & 21 have no factors in common, gcf=1
The greatest common factor in 3
The greatest common factor of 18 and 21 is 3.
The Greatest Common Factor of 14 and 21 is 7.
The least common factor is: 1
The greatest common factor of 6 and 21 is 3.

The greatest common factor (GCF) is 3.
It is 3
It is: 3

The greatest common factor of 6, 15 and 21 is 3. The prime factorization of 6 is 2*3 The prime factorization of 15 is 3*5 The prime factorization of 21 is 3*7 The GCF is then 3, as it is the only common factor.
The least common factor is: 1
the greatest common factor of 6 an 21 is 3 because 6's factors are 1,2, 3and 6 and 21's is 1,3,7, and 21. So the greatest one of those is 3.Yo its 3 :D
It is: 3
The least common factor of any set of numbers is 1.
