1. The gcf of 11 and 7 is 1, so the GCF of 10, 1015, 15, 11 & 7 cannot be any greater.
The GCF of 11 and 15 is 1. Since 11 is prime, it only has 11 and 1 as factors. Since 15 cannot be evenly divide by 11, the greatest common factor (GCF) is 1.
11 11*11 = 121 11*15 = 165
Since 11 is a prime number - the gcf can only be 1
The factors of 165 are:1, 3, 5, 11, 15, 33, 55, 165The factors of 231 are:1, 3, 7, 11, 21, 33, 77, 231The common factors are:1, 3, 11, 33The Greatest Common Factor (GCF) is:33
The GCF is 1.
The GCF is: 27
11 and 15 22
Factor out each term to get: 225 = 15 * 15 = 3² * 5² 165 = 15 * 11 = 3 * 5 * 11 Then, the GCF is 3 * 5 = 15 since that is the greatest term which divides both 225 and 165!
