Given numbers are 672, 687, 485, 654

The list of prime factors of all numbers are

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

Prime factors of 687 are 3 x 229

Prime factors of 485 are 5 x 97

Prime factors of 654 are 2 x 3 x 109

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

Given numbers are 672, 687, 485, 654

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

Apply this formula for all numbers.

Step1:

LCM(672, 687) = 153888

GCD(672, 687) = ( 672 x 687 ) / 153888

= 672 / 687

= 672

Step2:

LCM(3, 485) = 1455

GCD(3, 485) = ( 3 x 485 ) / 1455

= 3 / 485

= 3

Step3:

LCM(1, 654) = 654

GCD(1, 654) = ( 1 x 654 ) / 654

= 1 / 654

= 1

So, Greatest Common Divisor of 672, 687, 485, 654 is 1
