Given numbers are 392, 520, 57, 136

The list of prime factors of all numbers are

Prime factors of 392 are 2 x 2 x 2 x 7 x 7

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

Prime factors of 57 are 3 x 19

Prime factors of 136 are 2 x 2 x 2 x 17

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

Given numbers are 392, 520, 57, 136

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

Apply this formula for all numbers.

Step1:

LCM(392, 520) = 25480

GCD(392, 520) = ( 392 x 520 ) / 25480

= 392 / 520

= 392

Step2:

LCM(8, 57) = 456

GCD(8, 57) = ( 8 x 57 ) / 456

= 8 / 57

= 8

Step3:

LCM(1, 136) = 136

GCD(1, 136) = ( 1 x 136 ) / 136

= 1 / 136

= 1

So, Greatest Common Divisor of 392, 520, 57, 136 is 1
