Given numbers are 615, 351, 917, 809

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

Apply this formula for all numbers.

Step1:

LCM(615, 351) = 71955

GCD(615, 351) = ( 615 x 351 ) / 71955

= 615 / 351

= 615

Step2:

LCM(3, 917) = 2751

GCD(3, 917) = ( 3 x 917 ) / 2751

= 3 / 917

= 3

Step3:

LCM(1, 809) = 809

GCD(1, 809) = ( 1 x 809 ) / 809

= 1 / 809

= 1

So, Greatest Common Divisor of 615, 351, 917, 809 is 1
