Given numbers are 645, 431, 579, 632

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 431 are 431

Prime factors of 579 are 3 x 193

Prime factors of 632 are 2 x 2 x 2 x 79

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

Given numbers are 645, 431, 579, 632

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

Apply this formula for all numbers.

Step1:

LCM(645, 431) = 277995

GCD(645, 431) = ( 645 x 431 ) / 277995

= 645 / 431

= 645

Step2:

LCM(1, 579) = 579

GCD(1, 579) = ( 1 x 579 ) / 579

= 1 / 579

= 1

Step3:

LCM(1, 632) = 632

GCD(1, 632) = ( 1 x 632 ) / 632

= 1 / 632

= 1

So, Greatest Common Divisor of 645, 431, 579, 632 is 1
