Common factors are any numbers that are factors of each. The greatest common factor therefore is the largest number that appears in both lists. Factors of 52 1, 2, 4, 13, 26, 52 Factors of 84 1, 2, 3, 4, 6, 7, 12, 14, 28, 42, 84 Common factors would be - 4, 2, and 1 Therefore the greatest common factor is 4.
There are 2 factor pairs of 26.26 = 1 x 2626 = 2 x 13
First, you have to have a lowest common denominator. Eg: 1/2 - 6/13 The lowest common denominator is 26, because 13 * 2 is 26. You multiply 1/2 by 13, to make the denominator 26, which equals 13/26, then multiply 6/13 by 2 to get 12/26. So the equation with the lowest common denominators now plugged in is: 13/26 - 12/26 Subtract the numerators (13 and 12), so the answer is 1/26.
The Least Common Multiple (LCM) of 12, 26, and 39 is 156.
The only common factors I can see are 1 and 2. 18 is divisible by 1,2,3,6, and 9, and 26 is divisible by 1,2,13,and 26.
