Given numbers are 781, 142, 398, 935

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

Apply this formula for all numbers.

Step1:

LCM(781, 142) = 1562

GCD(781, 142) = ( 781 x 142 ) / 1562

= 781 / 142

= 781

Step2:

LCM(71, 398) = 28258

GCD(71, 398) = ( 71 x 398 ) / 28258

= 71 / 398

= 71

Step3:

LCM(1, 935) = 935

GCD(1, 935) = ( 1 x 935 ) / 935

= 1 / 935

= 1

So, Greatest Common Divisor of 781, 142, 398, 935 is 1
