Given numbers are 931, 420, 782, 811

The list of prime factors of all numbers are

Prime factors of 931 are 7 x 7 x 19

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 782 are 2 x 17 x 23

Prime factors of 811 are 811

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

Given numbers are 931, 420, 782, 811

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

Apply this formula for all numbers.

Step1:

LCM(931, 420) = 55860

GCD(931, 420) = ( 931 x 420 ) / 55860

= 931 / 420

= 931

Step2:

LCM(7, 782) = 5474

GCD(7, 782) = ( 7 x 782 ) / 5474

= 7 / 782

= 7

Step3:

LCM(1, 811) = 811

GCD(1, 811) = ( 1 x 811 ) / 811

= 1 / 811

= 1

So, Greatest Common Divisor of 931, 420, 782, 811 is 1
