2 numbers have a gcf of 3 = 3 & 6, 6 &9,...
You need at least two numbers. 18 and 36 among others.
6 = 2 x 3 9 = 3 x 3 15 = 3 x 5 GCF = 3
Factors of 4: 1, 2, 4 Factors of 9: 1, 3, 9 Factors of 16: 1, 2, 4, 8, 16 GCF (4, 9, 16) = 1
6and 9
GCF = 3 LCM = 18 Factors of 9: 1, 3, 9 Factors of 6: 1, 2, 3, 6 Multiples of 9: 9, 18 Multiples of 6: 6, 12, 18
The GCF is 3.
The GCF is 6.
The GCF of 9 and 6 is 3.
The Greatest Common Factor of 9, 36, 72: 9
The GCF of 2, 9 and 11 is 1. The LCM is 198.
the GCF for 6 and 9 is 3 because the factors for six are 1,2,3, and 6 and for 9 is 1,3, and 9 . Hope this help and I'm a teacher i teach at killian.
