Given numbers are 620, 458, 540, 286

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

Apply this formula for all numbers.

Step1:

LCM(620, 458) = 141980

GCD(620, 458) = ( 620 x 458 ) / 141980

= 620 / 458

= 620

Step2:

LCM(2, 540) = 540

GCD(2, 540) = ( 2 x 540 ) / 540

= 2 / 540

= 2

Step3:

LCM(2, 286) = 286

GCD(2, 286) = ( 2 x 286 ) / 286

= 2 / 286

= 2

So, Greatest Common Divisor of 620, 458, 540, 286 is 2
