Given numbers are 840, 606, 430, 154

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

Apply this formula for all numbers.

Step1:

LCM(840, 606) = 84840

GCD(840, 606) = ( 840 x 606 ) / 84840

= 840 / 606

= 840

Step2:

LCM(6, 430) = 1290

GCD(6, 430) = ( 6 x 430 ) / 1290

= 6 / 430

= 6

Step3:

LCM(2, 154) = 154

GCD(2, 154) = ( 2 x 154 ) / 154

= 2 / 154

= 2

So, Greatest Common Divisor of 840, 606, 430, 154 is 2
