To find the GCF of any two numbers, you need to figure out what numbers each have in common, then you choose the largest one that each have in common as the GCF. In this case: 15: 1, 3, 5, 15...then you have 22: 1, 2, 11...Not really much in common except the number 1; that is your GCF in this case. Good luck!
The GCF is 1.
22
Find out all the factors and then find the greatest common factor (gcf)...........very easy
The GCF is 22.
Any two composite numbers who do not share the same prime factors.15 = 5x322 = 11x2So 15 and 22 have a GCF of 1
The GCF of 12 15 and 22 is 1.
The GCF is: 1
The GCF is 1.
The GCF is 3.
The GCF is 1.
By noticing that 22 is a factor of 44 and therefore automatically the GCF of this problem.
22 is a factor of 110. 110 is a multiple of 22. That means that 22 is the GCF and 110 is the LCM of those two numbers.
The GCF of 10 and 15 is 5.
You need at least two numbers to find a GCF. IF that's 15 and 45, the GCF is 15.
The GCF is 2.
22
You need at least two numbers to find a GCF. If that's 15, 30 and 60, the GCF is 15.
