Given numbers are 645, 287, 765, 474

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 287 are 7 x 41

Prime factors of 765 are 3 x 3 x 5 x 17

Prime factors of 474 are 2 x 3 x 79

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

Given numbers are 645, 287, 765, 474

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

Apply this formula for all numbers.

Step1:

LCM(645, 287) = 185115

GCD(645, 287) = ( 645 x 287 ) / 185115

= 645 / 287

= 645

Step2:

LCM(1, 765) = 765

GCD(1, 765) = ( 1 x 765 ) / 765

= 1 / 765

= 1

Step3:

LCM(1, 474) = 474

GCD(1, 474) = ( 1 x 474 ) / 474

= 1 / 474

= 1

So, Greatest Common Divisor of 645, 287, 765, 474 is 1
