Given numbers are 987, 476, 121, 672

The list of prime factors of all numbers are

Prime factors of 987 are 3 x 7 x 47

Prime factors of 476 are 2 x 2 x 7 x 17

Prime factors of 121 are 11 x 11

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 987, 476, 121, 672

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

Apply this formula for all numbers.

Step1:

LCM(987, 476) = 67116

GCD(987, 476) = ( 987 x 476 ) / 67116

= 987 / 476

= 987

Step2:

LCM(7, 121) = 847

GCD(7, 121) = ( 7 x 121 ) / 847

= 7 / 121

= 7

Step3:

LCM(1, 672) = 672

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

= 1 / 672

= 1

So, Greatest Common Divisor of 987, 476, 121, 672 is 1
