Given numbers are 815, 707, 972, 403

The list of prime factors of all numbers are

Prime factors of 815 are 5 x 163

Prime factors of 707 are 7 x 101

Prime factors of 972 are 2 x 2 x 3 x 3 x 3 x 3 x 3

Prime factors of 403 are 13 x 31

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

Given numbers are 815, 707, 972, 403

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

Apply this formula for all numbers.

Step1:

LCM(815, 707) = 576205

GCD(815, 707) = ( 815 x 707 ) / 576205

= 815 / 707

= 815

Step2:

LCM(1, 972) = 972

GCD(1, 972) = ( 1 x 972 ) / 972

= 1 / 972

= 1

Step3:

LCM(1, 403) = 403

GCD(1, 403) = ( 1 x 403 ) / 403

= 1 / 403

= 1

So, Greatest Common Divisor of 815, 707, 972, 403 is 1
