Given numbers are 645, 504, 992, 431

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 504 are 2 x 2 x 2 x 3 x 3 x 7

Prime factors of 992 are 2 x 2 x 2 x 2 x 2 x 31

Prime factors of 431 are 431

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

Given numbers are 645, 504, 992, 431

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

Apply this formula for all numbers.

Step1:

LCM(645, 504) = 108360

GCD(645, 504) = ( 645 x 504 ) / 108360

= 645 / 504

= 645

Step2:

LCM(3, 992) = 2976

GCD(3, 992) = ( 3 x 992 ) / 2976

= 3 / 992

= 3

Step3:

LCM(1, 431) = 431

GCD(1, 431) = ( 1 x 431 ) / 431

= 1 / 431

= 1

So, Greatest Common Divisor of 645, 504, 992, 431 is 1
