Given numbers are 815, 432, 520, 961

The list of prime factors of all numbers are

Prime factors of 815 are 5 x 163

Prime factors of 432 are 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

Prime factors of 961 are 31 x 31

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

Given numbers are 815, 432, 520, 961

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

Apply this formula for all numbers.

Step1:

LCM(815, 432) = 352080

GCD(815, 432) = ( 815 x 432 ) / 352080

= 815 / 432

= 815

Step2:

LCM(1, 520) = 520

GCD(1, 520) = ( 1 x 520 ) / 520

= 1 / 520

= 1

Step3:

LCM(1, 961) = 961

GCD(1, 961) = ( 1 x 961 ) / 961

= 1 / 961

= 1

So, Greatest Common Divisor of 815, 432, 520, 961 is 1
