Given numbers are 857, 561, 696, 920

The list of prime factors of all numbers are

Prime factors of 857 are 857

Prime factors of 561 are 3 x 11 x 17

Prime factors of 696 are 2 x 2 x 2 x 3 x 29

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 857, 561, 696, 920

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

Apply this formula for all numbers.

Step1:

LCM(857, 561) = 480777

GCD(857, 561) = ( 857 x 561 ) / 480777

= 857 / 561

= 857

Step2:

LCM(1, 696) = 696

GCD(1, 696) = ( 1 x 696 ) / 696

= 1 / 696

= 1

Step3:

LCM(1, 920) = 920

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

= 1 / 920

= 1

So, Greatest Common Divisor of 857, 561, 696, 920 is 1
