Given numbers are 171, 451, 551, 672

The list of prime factors of all numbers are

Prime factors of 171 are 3 x 3 x 19

Prime factors of 451 are 11 x 41

Prime factors of 551 are 19 x 29

Prime factors of 672 are 2 x 2 x 2 x 2 x 2 x 3 x 7

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

Given numbers are 171, 451, 551, 672

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

Apply this formula for all numbers.

Step1:

LCM(171, 451) = 77121

GCD(171, 451) = ( 171 x 451 ) / 77121

= 171 / 451

= 171

Step2:

LCM(1, 551) = 551

GCD(1, 551) = ( 1 x 551 ) / 551

= 1 / 551

= 1

Step3:

LCM(1, 672) = 672

GCD(1, 672) = ( 1 x 672 ) / 672

= 1 / 672

= 1

So, Greatest Common Divisor of 171, 451, 551, 672 is 1
