Given numbers are 821, 427, 944, 672

The list of prime factors of all numbers are

Prime factors of 821 are 821

Prime factors of 427 are 7 x 61

Prime factors of 944 are 2 x 2 x 2 x 2 x 59

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 821, 427, 944, 672

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

Apply this formula for all numbers.

Step1:

LCM(821, 427) = 350567

GCD(821, 427) = ( 821 x 427 ) / 350567

= 821 / 427

= 821

Step2:

LCM(1, 944) = 944

GCD(1, 944) = ( 1 x 944 ) / 944

= 1 / 944

= 1

Step3:

LCM(1, 672) = 672

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

= 1 / 672

= 1

So, Greatest Common Divisor of 821, 427, 944, 672 is 1
