Given numbers are 645, 301, 492, 684

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 301 are 7 x 43

Prime factors of 492 are 2 x 2 x 3 x 41

Prime factors of 684 are 2 x 2 x 3 x 3 x 19

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

Given numbers are 645, 301, 492, 684

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

Apply this formula for all numbers.

Step1:

LCM(645, 301) = 4515

GCD(645, 301) = ( 645 x 301 ) / 4515

= 645 / 301

= 645

Step2:

LCM(43, 492) = 21156

GCD(43, 492) = ( 43 x 492 ) / 21156

= 43 / 492

= 43

Step3:

LCM(1, 684) = 684

GCD(1, 684) = ( 1 x 684 ) / 684

= 1 / 684

= 1

So, Greatest Common Divisor of 645, 301, 492, 684 is 1
