Given numbers are 156, 120, 645, 824

The list of prime factors of all numbers are

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 645 are 3 x 5 x 43

Prime factors of 824 are 2 x 2 x 2 x 103

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

Given numbers are 156, 120, 645, 824

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

Apply this formula for all numbers.

Step1:

LCM(156, 120) = 1560

GCD(156, 120) = ( 156 x 120 ) / 1560

= 156 / 120

= 156

Step2:

LCM(12, 645) = 2580

GCD(12, 645) = ( 12 x 645 ) / 2580

= 12 / 645

= 12

Step3:

LCM(3, 824) = 2472

GCD(3, 824) = ( 3 x 824 ) / 2472

= 3 / 824

= 3

So, Greatest Common Divisor of 156, 120, 645, 824 is 1
