Given numbers are 668, 406, 961

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

Apply this formula for all numbers.

Step1:

LCM(668, 406) = 135604

GCD(668, 406) = ( 668 x 406 ) / 135604

= 668 / 406

= 668

Step2:

LCM(2, 961) = 1922

GCD(2, 961) = ( 2 x 961 ) / 1922

= 2 / 961

= 2

So, Greatest Common Divisor of 668, 406, 961 is 1
