Given numbers are 938, 286, 623, 781

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

Apply this formula for all numbers.

Step1:

LCM(938, 286) = 134134

GCD(938, 286) = ( 938 x 286 ) / 134134

= 938 / 286

= 938

Step2:

LCM(2, 623) = 1246

GCD(2, 623) = ( 2 x 623 ) / 1246

= 2 / 623

= 2

Step3:

LCM(1, 781) = 781

GCD(1, 781) = ( 1 x 781 ) / 781

= 1 / 781

= 1

So, Greatest Common Divisor of 938, 286, 623, 781 is 1
