Given numbers are 649, 286, 368, 418

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

Apply this formula for all numbers.

Step1:

LCM(649, 286) = 16874

GCD(649, 286) = ( 649 x 286 ) / 16874

= 649 / 286

= 649

Step2:

LCM(11, 368) = 4048

GCD(11, 368) = ( 11 x 368 ) / 4048

= 11 / 368

= 11

Step3:

LCM(1, 418) = 418

GCD(1, 418) = ( 1 x 418 ) / 418

= 1 / 418

= 1

So, Greatest Common Divisor of 649, 286, 368, 418 is 1
