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

Apply this formula for all numbers.

Step1:

LCM(630, 294) = 4410

GCD(630, 294) = ( 630 x 294 ) / 4410

= 630 / 294

= 630

Step2:

LCM(42, 847) = 5082

GCD(42, 847) = ( 42 x 847 ) / 5082

= 42 / 847

= 42

Step3:

LCM(7, 161) = 161

GCD(7, 161) = ( 7 x 161 ) / 161

= 7 / 161

= 7

So, Greatest Common Divisor of 630, 294, 847, 161 is 7
