Given numbers are 159, 630, 140, 920

The list of prime factors of all numbers are

Prime factors of 159 are 3 x 53

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

Prime factors of 140 are 2 x 2 x 5 x 7

Prime factors of 920 are 2 x 2 x 2 x 5 x 23

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

Given numbers are 159, 630, 140, 920

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

Apply this formula for all numbers.

Step1:

LCM(159, 630) = 33390

GCD(159, 630) = ( 159 x 630 ) / 33390

= 159 / 630

= 159

Step2:

LCM(3, 140) = 420

GCD(3, 140) = ( 3 x 140 ) / 420

= 3 / 140

= 3

Step3:

LCM(1, 920) = 920

GCD(1, 920) = ( 1 x 920 ) / 920

= 1 / 920

= 1

So, Greatest Common Divisor of 159, 630, 140, 920 is 1
