The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 938, 498, 560, 643

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

Apply this formula for all numbers.

Step1:

LCM(938, 498) = 233562

GCD(938, 498) = ( 938 x 498 ) / 233562

= 938 / 498

= 938

Step2:

LCM(2, 560) = 560

GCD(2, 560) = ( 2 x 560 ) / 560

= 2 / 560

= 2

Step3:

LCM(2, 643) = 1286

GCD(2, 643) = ( 2 x 643 ) / 1286

= 2 / 643

= 2

So, Greatest Common Divisor of 938, 498, 560, 643 is 1
