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

Apply this formula for all numbers.

Step1:

LCM(689, 961) = 662129

GCD(689, 961) = ( 689 x 961 ) / 662129

= 689 / 961

= 689

Step2:

LCM(1, 248) = 248

GCD(1, 248) = ( 1 x 248 ) / 248

= 1 / 248

= 1

So, Greatest Common Divisor of 689, 961, 248 is 1
