Given numbers are 645, 232, 671, 727

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 232 are 2 x 2 x 2 x 29

Prime factors of 671 are 11 x 61

Prime factors of 727 are 727

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

Given numbers are 645, 232, 671, 727

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

Apply this formula for all numbers.

Step1:

LCM(645, 232) = 149640

GCD(645, 232) = ( 645 x 232 ) / 149640

= 645 / 232

= 645

Step2:

LCM(1, 671) = 671

GCD(1, 671) = ( 1 x 671 ) / 671

= 1 / 671

= 1

Step3:

LCM(1, 727) = 727

GCD(1, 727) = ( 1 x 727 ) / 727

= 1 / 727

= 1

So, Greatest Common Divisor of 645, 232, 671, 727 is 1
