Question

Hello,please solve it

Is 14 a factor of 42 and 112? Is 14 a factor of (112 + 42) and (112 - 42)?

Answer 1

Solution:-
Factors of 42 = 1, 2, 3, 6, 7, 14, 21 and 42
Factors of 112 = 1, 2, 4, 7, 8, 14, 16, 28, 56 and 112
Hence 14 is a factor of 42 and 112.
(112+42) = 154
Factors of 154 = 1, 2, 7, 11, 14, 22, 77 and 154
(112 - 42) = 70
Factors of 70 = 1, 2, 5, 7, 10,14, 35 and 70
Hence 14 is a factor of 154 and 70 also.
