The greatest common factor of 90 , 77 = 1
The Greatest Common Factor (GCF) is: 7. Find the factors of each one, then multiply the common ones together to get GCF:77 = 11 * 7 * 114 = 7 * 2 * 1 (one is always a factor)So the GCF = 7 * 1 = 7. Why list the number 1, well how about the GCF of 8 and 5.First let's not list the number 1:8 = 2 * 2 * 25 = 5It might look like the two numbers don't have any common factors, but the number 1 is a factor of every other number, so in this case the GCF would be 1.
