Given numbers are 831, 965, 813, 620

The list of prime factors of all numbers are

Prime factors of 831 are 3 x 277

Prime factors of 965 are 5 x 193

Prime factors of 813 are 3 x 271

Prime factors of 620 are 2 x 2 x 5 x 31

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

Given numbers are 831, 965, 813, 620

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

Apply this formula for all numbers.

Step1:

LCM(831, 965) = 801915

GCD(831, 965) = ( 831 x 965 ) / 801915

= 831 / 965

= 831

Step2:

LCM(1, 813) = 813

GCD(1, 813) = ( 1 x 813 ) / 813

= 1 / 813

= 1

Step3:

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

= 1 / 620

= 1

So, Greatest Common Divisor of 831, 965, 813, 620 is 1
