Given numbers are 978, 618, 685

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

Apply this formula for all numbers.

Step1:

LCM(978, 618) = 100734

GCD(978, 618) = ( 978 x 618 ) / 100734

= 978 / 618

= 978

Step2:

LCM(6, 685) = 4110

GCD(6, 685) = ( 6 x 685 ) / 4110

= 6 / 685

= 6

So, Greatest Common Divisor of 978, 618, 685 is 1
