Given numbers are 294, 698, 688, 643

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

Apply this formula for all numbers.

Step1:

LCM(294, 698) = 102606

GCD(294, 698) = ( 294 x 698 ) / 102606

= 294 / 698

= 294

Step2:

LCM(2, 688) = 688

GCD(2, 688) = ( 2 x 688 ) / 688

= 2 / 688

= 2

Step3:

LCM(2, 643) = 1286

GCD(2, 643) = ( 2 x 643 ) / 1286

= 2 / 643

= 2

So, Greatest Common Divisor of 294, 698, 688, 643 is 1
