Given numbers are 462, 396, 637, 120

The list of prime factors of all numbers are

Prime factors of 462 are 2 x 3 x 7 x 11

Prime factors of 396 are 2 x 2 x 3 x 3 x 11

Prime factors of 637 are 7 x 7 x 13

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

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

Given numbers are 462, 396, 637, 120

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

Apply this formula for all numbers.

Step1:

LCM(462, 396) = 2772

GCD(462, 396) = ( 462 x 396 ) / 2772

= 462 / 396

= 462

Step2:

LCM(66, 637) = 42042

GCD(66, 637) = ( 66 x 637 ) / 42042

= 66 / 637

= 66

Step3:

LCM(1, 120) = 120

GCD(1, 120) = ( 1 x 120 ) / 120

= 1 / 120

= 1

So, Greatest Common Divisor of 462, 396, 637, 120 is 1
