Given numbers are 312, 645, 689, 227

The list of prime factors of all numbers are

Prime factors of 312 are 2 x 2 x 2 x 3 x 13

Prime factors of 645 are 3 x 5 x 43

Prime factors of 689 are 13 x 53

Prime factors of 227 are 227

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

Given numbers are 312, 645, 689, 227

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

Apply this formula for all numbers.

Step1:

LCM(312, 645) = 67080

GCD(312, 645) = ( 312 x 645 ) / 67080

= 312 / 645

= 312

Step2:

LCM(3, 689) = 2067

GCD(3, 689) = ( 3 x 689 ) / 2067

= 3 / 689

= 3

Step3:

LCM(1, 227) = 227

GCD(1, 227) = ( 1 x 227 ) / 227

= 1 / 227

= 1

So, Greatest Common Divisor of 312, 645, 689, 227 is 1
