The GCF is 2.
It is: 2*8 = 16
22 x 3 = 12, the GCF
The GCF of 4, 12, 22 and 30 is 2.
22 is the GCF of 66 and 22.
This is confusingly written. I think that someone wants you to learn the fact that the product of two numbers is equal to the product of their LCM and GCF. Example: 6 and 8 GCF = 2 LCM = 24 6 x 8 = 48 2 x 24 = 48 So 22 x 23 = 506 If the GCF is 2, then the LCM is 253. But the GCF of 22 and 23 isn't 2. And 253 isn't a multiple of 22 or 23. And 22 and 23 wouldn't be the factors of two numbers. This may not have been copied correctly.
The GCF is 11.
GCF(22, 16) = 2
The GCF of 12 15 and 22 is 1.
The GCF is 2.
The GCF is 2.
The GCF of 16, 22, and 24 is 2.
Gcf = 2 LCM = 132
The GCF of 4, 12, and 22 is 2.
12 x 22 = 264
22 x 3 = 12, the GCF
The GCF of 4, 12, 22 and 30 is 2.
16 = 24 100 = 22 x 52 So their GCF is 22 = 4
The GCF is 2.
