Given numbers are 402, 721, 818

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

Apply this formula for all numbers.

Step1:

LCM(402, 721) = 289842

GCD(402, 721) = ( 402 x 721 ) / 289842

= 402 / 721

= 402

Step2:

LCM(1, 818) = 818

GCD(1, 818) = ( 1 x 818 ) / 818

= 1 / 818

= 1

So, Greatest Common Divisor of 402, 721, 818 is 1
