Given numbers are 813, 783, 991, 924

The list of prime factors of all numbers are

Prime factors of 813 are 3 x 271

Prime factors of 783 are 3 x 3 x 3 x 29

Prime factors of 991 are 991

Prime factors of 924 are 2 x 2 x 3 x 7 x 11

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

Given numbers are 813, 783, 991, 924

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

Apply this formula for all numbers.

Step1:

LCM(813, 783) = 212193

GCD(813, 783) = ( 813 x 783 ) / 212193

= 813 / 783

= 813

Step2:

LCM(3, 991) = 2973

GCD(3, 991) = ( 3 x 991 ) / 2973

= 3 / 991

= 3

Step3:

LCM(1, 924) = 924

GCD(1, 924) = ( 1 x 924 ) / 924

= 1 / 924

= 1

So, Greatest Common Divisor of 813, 783, 991, 924 is 1
