The factors of 26 are:1, 2, 13, 26The factors of 42 are:1, 2, 3, 6, 7, 14, 21, 42The Greatest Common Factor:GCF = 2
The GCF of 26, 42, and 78 is 2.The factors of 26 are: 1, 2, 13, 26The factors of 42 are: 1, 2, 3, 6, 7, 14, 21, 42The factors of 78 are: 1, 2, 3, 6, 13, 26, 39, 78The common factors are: 1, 2The Greatest Common Factor (GCF) is: 2
To find the LCM of 26 and 42 you first need to break those numbers up into their prime factors. In this case, that would be: 26 = 2x13 42 = 2x3x7 The next step is to identify any common factors. In this case, both numbers have a 2 as a prime factor, so we can discard one of these. Take every other prime factor (2, 3, 7 and 13) and multiply them together to find the LCM: 2x3x7x13 = 546 Therefore the LCM of 26 and 42 is 546.
1,2,3,6,7,14,21,42 6,14,21 and 42 are composite.
No. A prime number has only two factors, 1 and itself. However 42 has other factors: 1 x 42 = 42 2 x 26 = 42 3 x 14 = 42 6 x 7 = 42
26 and 19 are both factors of 494.
