Find the GCF of 63, 147, and 273
You can use prime factorisation to find the GCF of these integers.
63 = 3*3*7
147 = 3*7*7
273 = 3*7*13
Now select the factors that are common to the three lists of prime factors and multiply them.
These are 3 and 7
So the GCF = 3*7 = 21
Check:
63 = 3*21
147 = 7*21
273 = 13*21
