Given numbers are 156, 120, 326, 989

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 326 are 2 x 163

Prime factors of 989 are 23 x 43

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

Given numbers are 156, 120, 326, 989

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, 326) = 1956

GCD(12, 326) = ( 12 x 326 ) / 1956

= 12 / 326

= 12

Step3:

LCM(2, 989) = 1978

GCD(2, 989) = ( 2 x 989 ) / 1978

= 2 / 989

= 2

So, Greatest Common Divisor of 156, 120, 326, 989 is 1
