Given numbers are 442, 156, 120, 457

The list of prime factors of all numbers are

Prime factors of 442 are 2 x 13 x 17

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

Prime factors of 120 are 2 x 2 x 2 x 3 x 5

Prime factors of 457 are 457

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

Given numbers are 442, 156, 120, 457

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

Apply this formula for all numbers.

Step1:

LCM(442, 156) = 2652

GCD(442, 156) = ( 442 x 156 ) / 2652

= 442 / 156

= 442

Step2:

LCM(26, 120) = 1560

GCD(26, 120) = ( 26 x 120 ) / 1560

= 26 / 120

= 26

Step3:

LCM(2, 457) = 914

GCD(2, 457) = ( 2 x 457 ) / 914

= 2 / 457

= 2

So, Greatest Common Divisor of 442, 156, 120, 457 is 1
