Given numbers are 645, 848, 702, 272

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 848 are 2 x 2 x 2 x 2 x 53

Prime factors of 702 are 2 x 3 x 3 x 3 x 13

Prime factors of 272 are 2 x 2 x 2 x 2 x 17

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

Given numbers are 645, 848, 702, 272

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

Apply this formula for all numbers.

Step1:

LCM(645, 848) = 546960

GCD(645, 848) = ( 645 x 848 ) / 546960

= 645 / 848

= 645

Step2:

LCM(1, 702) = 702

GCD(1, 702) = ( 1 x 702 ) / 702

= 1 / 702

= 1

Step3:

LCM(1, 272) = 272

GCD(1, 272) = ( 1 x 272 ) / 272

= 1 / 272

= 1

So, Greatest Common Divisor of 645, 848, 702, 272 is 1
