Given numbers are 831, 780, 441, 406

The list of prime factors of all numbers are

Prime factors of 831 are 3 x 277

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 441 are 3 x 3 x 7 x 7

Prime factors of 406 are 2 x 7 x 29

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

Given numbers are 831, 780, 441, 406

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

Apply this formula for all numbers.

Step1:

LCM(831, 780) = 216060

GCD(831, 780) = ( 831 x 780 ) / 216060

= 831 / 780

= 831

Step2:

LCM(3, 441) = 441

GCD(3, 441) = ( 3 x 441 ) / 441

= 3 / 441

= 3

Step3:

LCM(3, 406) = 1218

GCD(3, 406) = ( 3 x 406 ) / 1218

= 3 / 406

= 3

So, Greatest Common Divisor of 831, 780, 441, 406 is 1
