Given numbers are 671, 612, 642, 147

The list of prime factors of all numbers are

Prime factors of 671 are 11 x 61

Prime factors of 612 are 2 x 2 x 3 x 3 x 17

Prime factors of 642 are 2 x 3 x 107

Prime factors of 147 are 3 x 7 x 7

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

Given numbers are 671, 612, 642, 147

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

Apply this formula for all numbers.

Step1:

LCM(671, 612) = 410652

GCD(671, 612) = ( 671 x 612 ) / 410652

= 671 / 612

= 671

Step2:

LCM(1, 642) = 642

GCD(1, 642) = ( 1 x 642 ) / 642

= 1 / 642

= 1

Step3:

LCM(1, 147) = 147

GCD(1, 147) = ( 1 x 147 ) / 147

= 1 / 147

= 1

So, Greatest Common Divisor of 671, 612, 642, 147 is 1
