The GCF or greatest common factor of 11 and 5 is 1.
It is 5
It is: 5
The GCF is 5.
130
3 x 3 x 11 = 99 3 x 5 x 11 = 165 3 x 11 = 33, the GCF
99900
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.
2 * 5 * 5 * 11= 550
2 x 4 x 5 x 11 = 440
1, 3, 5, 15.
