Given numbers are 681, 778, 615

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

Apply this formula for all numbers.

Step1:

LCM(681, 778) = 529818

GCD(681, 778) = ( 681 x 778 ) / 529818

= 681 / 778

= 681

Step2:

LCM(1, 615) = 615

GCD(1, 615) = ( 1 x 615 ) / 615

= 1 / 615

= 1

So, Greatest Common Divisor of 681, 778, 615 is 1
