Given numbers are 797, 831, 840, 620

The list of prime factors of all numbers are

Prime factors of 797 are 797

Prime factors of 831 are 3 x 277

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

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 797, 831, 840, 620

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

Apply this formula for all numbers.

Step1:

LCM(797, 831) = 662307

GCD(797, 831) = ( 797 x 831 ) / 662307

= 797 / 831

= 797

Step2:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

Step3:

LCM(1, 620) = 620

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

= 1 / 620

= 1

So, Greatest Common Divisor of 797, 831, 840, 620 is 1
