Given numbers are 615, 222, 820

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

Apply this formula for all numbers.

Step1:

LCM(615, 222) = 45510

GCD(615, 222) = ( 615 x 222 ) / 45510

= 615 / 222

= 615

Step2:

LCM(3, 820) = 2460

GCD(3, 820) = ( 3 x 820 ) / 2460

= 3 / 820

= 3

So, Greatest Common Divisor of 615, 222, 820 is 1
