The GCF is 1.
The least common factor is: 1
The only common factor is 1.
The highest common factor is 13.(13 * 11 = 143)(13 * 18 = 234)
The greatest common factor (GCF) is: 1
1 is a common factor of 11, 12, 13, 14 and 15.
The GCF is 1.
The GCF of 11, 13 and 24 is 1.
The GCF of 143 and 169 is 13. One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them. The factors of 143 are 1, 11, 13, and 143. The factors of 169 are 1, 13, and 169. The common factors are 1 and 13. Therefore, the greatest common factor is 13.
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 only common factor of these numbers is 1.
66=1*2*3*11 121=11*11 143=11*13 highest common factor is 11
It can be. 13 is a common factor of 26 and 39.
