Find the GCF for 25, 35, and 45
The prime factors are:
25=5*5
35=5*7
45=3*3*5
All three numbers only have a common factor of 5.
The GCF=5
:
Another way of looking at GCF's is to find the biggest number that divides evenly into all three numbers. They all end in 5, so they all are divisible by 5.
and and
5,7, and 9 don't have any factors in common, so the GCF is 5.
Happy Calculating!!!
