Given numbers are 278, 912, 49, 156

The list of prime factors of all numbers are

Prime factors of 278 are 2 x 139

Prime factors of 912 are 2 x 2 x 2 x 2 x 3 x 19

Prime factors of 49 are 7 x 7

Prime factors of 156 are 2 x 2 x 3 x 13

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 278, 912, 49, 156

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(278, 912) = 126768

GCD(278, 912) = ( 278 x 912 ) / 126768

= 278 / 912

= 278

Step2:

LCM(2, 49) = 98

GCD(2, 49) = ( 2 x 49 ) / 98

= 2 / 49

= 2

Step3:

LCM(1, 156) = 156

GCD(1, 156) = ( 1 x 156 ) / 156

= 1 / 156

= 1

So, Greatest Common Divisor of 278, 912, 49, 156 is 1
