Given numbers are 677, 630, 558, 147

The list of prime factors of all numbers are

Prime factors of 677 are 677

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

Prime factors of 558 are 2 x 3 x 3 x 31

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 677, 630, 558, 147

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

Apply this formula for all numbers.

Step1:

LCM(677, 630) = 426510

GCD(677, 630) = ( 677 x 630 ) / 426510

= 677 / 630

= 677

Step2:

LCM(1, 558) = 558

GCD(1, 558) = ( 1 x 558 ) / 558

= 1 / 558

= 1

Step3:

LCM(1, 147) = 147

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

= 1 / 147

= 1

So, Greatest Common Divisor of 677, 630, 558, 147 is 1
