The GCF would be 4xy because you would have to find the biggest multiple for 20xy and 24xyz, which is 4xy
Answer:
4xy is GCF.
Step-by-step explanation:
Given : 20xy and 24xyz
To find : what is the GCF
Solution : We have given 20xy and 24xyz
Steps to find GCF ( greatest common factors)
Step 1: Prime factor of each number
20 xy = 1 * 2 * 4* 5* 20 * x * y .
24 xyz = 1 *2 *3 * 4 * 6* 8 * 12 *24 * x *y *z .
We can see the common factors are 1 ,2, 4, x ,y
So in these common factors 4 xy is greatest common factor.
Therefore, 4xy is GCF.
