Given numbers are 476, 765, 831, 645

The list of prime factors of all numbers are

Prime factors of 476 are 2 x 2 x 7 x 17

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

Prime factors of 831 are 3 x 277

Prime factors of 645 are 3 x 5 x 43

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

Given numbers are 476, 765, 831, 645

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

Apply this formula for all numbers.

Step1:

LCM(476, 765) = 21420

GCD(476, 765) = ( 476 x 765 ) / 21420

= 476 / 765

= 476

Step2:

LCM(17, 831) = 14127

GCD(17, 831) = ( 17 x 831 ) / 14127

= 17 / 831

= 17

Step3:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 476, 765, 831, 645 is 1
