Given numbers are 715, 561, 855, 576

The list of prime factors of all numbers are

Prime factors of 715 are 5 x 11 x 13

Prime factors of 561 are 3 x 11 x 17

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 576 are 2 x 2 x 2 x 2 x 2 x 2 x 3 x 3

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

Given numbers are 715, 561, 855, 576

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

Apply this formula for all numbers.

Step1:

LCM(715, 561) = 36465

GCD(715, 561) = ( 715 x 561 ) / 36465

= 715 / 561

= 715

Step2:

LCM(11, 855) = 9405

GCD(11, 855) = ( 11 x 855 ) / 9405

= 11 / 855

= 11

Step3:

LCM(1, 576) = 576

GCD(1, 576) = ( 1 x 576 ) / 576

= 1 / 576

= 1

So, Greatest Common Divisor of 715, 561, 855, 576 is 1
