Given numbers are 813, 661, 480, 386

The list of prime factors of all numbers are

Prime factors of 813 are 3 x 271

Prime factors of 661 are 661

Prime factors of 480 are 2 x 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 386 are 2 x 193

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

Given numbers are 813, 661, 480, 386

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

Apply this formula for all numbers.

Step1:

LCM(813, 661) = 537393

GCD(813, 661) = ( 813 x 661 ) / 537393

= 813 / 661

= 813

Step2:

LCM(1, 480) = 480

GCD(1, 480) = ( 1 x 480 ) / 480

= 1 / 480

= 1

Step3:

LCM(1, 386) = 386

GCD(1, 386) = ( 1 x 386 ) / 386

= 1 / 386

= 1

So, Greatest Common Divisor of 813, 661, 480, 386 is 1
