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

Apply this formula for all numbers.

Step1:

LCM(294, 840) = 5880

GCD(294, 840) = ( 294 x 840 ) / 5880

= 294 / 840

= 294

Step2:

LCM(42, 687) = 9618

GCD(42, 687) = ( 42 x 687 ) / 9618

= 42 / 687

= 42

Step3:

LCM(3, 315) = 315

GCD(3, 315) = ( 3 x 315 ) / 315

= 3 / 315

= 3

So, Greatest Common Divisor of 294, 840, 687, 315 is 3
