Given numbers are 645, 715, 456, 873

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 715 are 5 x 11 x 13

Prime factors of 456 are 2 x 2 x 2 x 3 x 19

Prime factors of 873 are 3 x 3 x 97

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

Given numbers are 645, 715, 456, 873

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

Apply this formula for all numbers.

Step1:

LCM(645, 715) = 92235

GCD(645, 715) = ( 645 x 715 ) / 92235

= 645 / 715

= 645

Step2:

LCM(5, 456) = 2280

GCD(5, 456) = ( 5 x 456 ) / 2280

= 5 / 456

= 5

Step3:

LCM(1, 873) = 873

GCD(1, 873) = ( 1 x 873 ) / 873

= 1 / 873

= 1

So, Greatest Common Divisor of 645, 715, 456, 873 is 1
