Given numbers are 808, 462, 615, 861

The list of prime factors of all numbers are

Prime factors of 808 are 2 x 2 x 2 x 101

Prime factors of 462 are 2 x 3 x 7 x 11

Prime factors of 615 are 3 x 5 x 41

Prime factors of 861 are 3 x 7 x 41

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

Given numbers are 808, 462, 615, 861

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

Apply this formula for all numbers.

Step1:

LCM(808, 462) = 186648

GCD(808, 462) = ( 808 x 462 ) / 186648

= 808 / 462

= 808

Step2:

LCM(2, 615) = 1230

GCD(2, 615) = ( 2 x 615 ) / 1230

= 2 / 615

= 2

Step3:

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

= 1 / 861

= 1

So, Greatest Common Divisor of 808, 462, 615, 861 is 1
