Given numbers are 610, 342, 640, 434

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

Apply this formula for all numbers.

Step1:

LCM(610, 342) = 104310

GCD(610, 342) = ( 610 x 342 ) / 104310

= 610 / 342

= 610

Step2:

LCM(2, 640) = 640

GCD(2, 640) = ( 2 x 640 ) / 640

= 2 / 640

= 2

Step3:

LCM(2, 434) = 434

GCD(2, 434) = ( 2 x 434 ) / 434

= 2 / 434

= 2

So, Greatest Common Divisor of 610, 342, 640, 434 is 2
