Given numbers are 663, 962, 639, 693

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

Apply this formula for all numbers.

Step1:

LCM(663, 962) = 49062

GCD(663, 962) = ( 663 x 962 ) / 49062

= 663 / 962

= 663

Step2:

LCM(13, 639) = 8307

GCD(13, 639) = ( 13 x 639 ) / 8307

= 13 / 639

= 13

Step3:

LCM(1, 693) = 693

GCD(1, 693) = ( 1 x 693 ) / 693

= 1 / 693

= 1

So, Greatest Common Divisor of 663, 962, 639, 693 is 1
