Given numbers are 140, 184, 286, 648

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

Apply this formula for all numbers.

Step1:

LCM(140, 184) = 6440

GCD(140, 184) = ( 140 x 184 ) / 6440

= 140 / 184

= 140

Step2:

LCM(4, 286) = 572

GCD(4, 286) = ( 4 x 286 ) / 572

= 4 / 286

= 4

Step3:

LCM(2, 648) = 648

GCD(2, 648) = ( 2 x 648 ) / 648

= 2 / 648

= 2

So, Greatest Common Divisor of 140, 184, 286, 648 is 2
