Given numbers are 645, 425, 758, 404

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 425 are 5 x 5 x 17

Prime factors of 758 are 2 x 379

Prime factors of 404 are 2 x 2 x 101

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

Given numbers are 645, 425, 758, 404

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

Apply this formula for all numbers.

Step1:

LCM(645, 425) = 54825

GCD(645, 425) = ( 645 x 425 ) / 54825

= 645 / 425

= 645

Step2:

LCM(5, 758) = 3790

GCD(5, 758) = ( 5 x 758 ) / 3790

= 5 / 758

= 5

Step3:

LCM(1, 404) = 404

GCD(1, 404) = ( 1 x 404 ) / 404

= 1 / 404

= 1

So, Greatest Common Divisor of 645, 425, 758, 404 is 1
