Factor the numbers into primes:
55 = 5 * 11
143 = 13 * 11
110 = 2 * 5 * 11
The ONLY factor they all have in common is 11. 11 is the greatest (and only) common factor.
The GCF is 11.
The GCF is 11.
Since 55 is a factor of 110, it is automatically the GCF.
The GCF is 11.
The Greatest Common Factor of 165 and 110 are is 55.
The GCF is 1.
55 is the greatest common factor of 55 and 110
The GCF is 55.
The GCF is 11.
The GCF is 11.
The factors of 143 are:1, 11, 13, 143The factors of 220 are:1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220The common factors are:1, 11Therefore, the Greatest Common Factor (GCF) is: 11
It is 11
