Given numbers are 203, 931, 405, 418

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

Apply this formula for all numbers.

Step1:

LCM(203, 931) = 26999

GCD(203, 931) = ( 203 x 931 ) / 26999

= 203 / 931

= 203

Step2:

LCM(7, 405) = 2835

GCD(7, 405) = ( 7 x 405 ) / 2835

= 7 / 405

= 7

Step3:

LCM(1, 418) = 418

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

= 1 / 418

= 1

So, Greatest Common Divisor of 203, 931, 405, 418 is 1
