The GCF is 1.
Factors of 69: 1, 3, 23, 69 Factors of 21: 1, 3, 7, 21 GCF (69, 21) = 3
The GCF is 23.
GCF(23, 69, 92) = 23. Listing 69 twice makes no difference.
The GCF is 23.
Greatest common factor of a and b is a if b is divisible by a.Here, 69 is divisible by 23 therefore GCF is 23.
The GCF is 23.
The GCF is 23.
Since 69 is a factor of 207, it will automatically be the GCF of this problem. But let's do it correctly. 3 x 23 = 69 3 x 3 x 23 = 207 Select the common factors. 3 x 23 = 69, the GCF.
It can be. 69 is the GCF of 138 and 207.
The GCF is 3.
