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

Apply this formula for all numbers.

Step1:

LCM(978, 791) = 773598

GCD(978, 791) = ( 978 x 791 ) / 773598

= 978 / 791

= 978

Step2:

LCM(1, 498) = 498

GCD(1, 498) = ( 1 x 498 ) / 498

= 1 / 498

= 1

So, Greatest Common Divisor of 978, 791, 498 is 1
