Given numbers are 815, 756, 567, 920

The list of prime factors of all numbers are

Prime factors of 815 are 5 x 163

Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7

Prime factors of 567 are 3 x 3 x 3 x 3 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 815, 756, 567, 920

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

Apply this formula for all numbers.

Step1:

LCM(815, 756) = 616140

GCD(815, 756) = ( 815 x 756 ) / 616140

= 815 / 756

= 815

Step2:

LCM(1, 567) = 567

GCD(1, 567) = ( 1 x 567 ) / 567

= 1 / 567

= 1

Step3:

LCM(1, 920) = 920

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

= 1 / 920

= 1

So, Greatest Common Divisor of 815, 756, 567, 920 is 1
