Given numbers are 981, 470, 421, 672

The list of prime factors of all numbers are

Prime factors of 981 are 3 x 3 x 109

Prime factors of 470 are 2 x 5 x 47

Prime factors of 421 are 421

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 981, 470, 421, 672

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

Apply this formula for all numbers.

Step1:

LCM(981, 470) = 461070

GCD(981, 470) = ( 981 x 470 ) / 461070

= 981 / 470

= 981

Step2:

LCM(1, 421) = 421

GCD(1, 421) = ( 1 x 421 ) / 421

= 1 / 421

= 1

Step3:

LCM(1, 672) = 672

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

= 1 / 672

= 1

So, Greatest Common Divisor of 981, 470, 421, 672 is 1
