Given numbers are 813, 520, 744, 478

The list of prime factors of all numbers are

Prime factors of 813 are 3 x 271

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

Prime factors of 744 are 2 x 2 x 2 x 3 x 31

Prime factors of 478 are 2 x 239

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

Given numbers are 813, 520, 744, 478

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

Apply this formula for all numbers.

Step1:

LCM(813, 520) = 422760

GCD(813, 520) = ( 813 x 520 ) / 422760

= 813 / 520

= 813

Step2:

LCM(1, 744) = 744

GCD(1, 744) = ( 1 x 744 ) / 744

= 1 / 744

= 1

Step3:

LCM(1, 478) = 478

GCD(1, 478) = ( 1 x 478 ) / 478

= 1 / 478

= 1

So, Greatest Common Divisor of 813, 520, 744, 478 is 1
