Given numbers are 663, 426, 974, 635

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

Apply this formula for all numbers.

Step1:

LCM(663, 426) = 94146

GCD(663, 426) = ( 663 x 426 ) / 94146

= 663 / 426

= 663

Step2:

LCM(3, 974) = 2922

GCD(3, 974) = ( 3 x 974 ) / 2922

= 3 / 974

= 3

Step3:

LCM(1, 635) = 635

GCD(1, 635) = ( 1 x 635 ) / 635

= 1 / 635

= 1

So, Greatest Common Divisor of 663, 426, 974, 635 is 1
