Given numbers are 645, 308, 267, 652

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 308 are 2 x 2 x 7 x 11

Prime factors of 267 are 3 x 89

Prime factors of 652 are 2 x 2 x 163

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

Given numbers are 645, 308, 267, 652

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

Apply this formula for all numbers.

Step1:

LCM(645, 308) = 198660

GCD(645, 308) = ( 645 x 308 ) / 198660

= 645 / 308

= 645

Step2:

LCM(1, 267) = 267

GCD(1, 267) = ( 1 x 267 ) / 267

= 1 / 267

= 1

Step3:

LCM(1, 652) = 652

GCD(1, 652) = ( 1 x 652 ) / 652

= 1 / 652

= 1

So, Greatest Common Divisor of 645, 308, 267, 652 is 1
