Given numbers are 815, 981, 618

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

Apply this formula for all numbers.

Step1:

LCM(815, 981) = 799515

GCD(815, 981) = ( 815 x 981 ) / 799515

= 815 / 981

= 815

Step2:

LCM(1, 618) = 618

GCD(1, 618) = ( 1 x 618 ) / 618

= 1 / 618

= 1

So, Greatest Common Divisor of 815, 981, 618 is 1
