Given numbers are 645, 715, 428, 650

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 428 are 2 x 2 x 107

Prime factors of 650 are 2 x 5 x 5 x 13

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

Given numbers are 645, 715, 428, 650

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, 428) = 2140

GCD(5, 428) = ( 5 x 428 ) / 2140

= 5 / 428

= 5

Step3:

LCM(1, 650) = 650

GCD(1, 650) = ( 1 x 650 ) / 650

= 1 / 650

= 1

So, Greatest Common Divisor of 645, 715, 428, 650 is 1
