Given numbers are 646, 221, 938, 741

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

Apply this formula for all numbers.

Step1:

LCM(646, 221) = 8398

GCD(646, 221) = ( 646 x 221 ) / 8398

= 646 / 221

= 646

Step2:

LCM(17, 938) = 15946

GCD(17, 938) = ( 17 x 938 ) / 15946

= 17 / 938

= 17

Step3:

LCM(1, 741) = 741

GCD(1, 741) = ( 1 x 741 ) / 741

= 1 / 741

= 1

So, Greatest Common Divisor of 646, 221, 938, 741 is 1
