Given numbers are 781, 639, 944

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

Apply this formula for all numbers.

Step1:

LCM(781, 639) = 7029

GCD(781, 639) = ( 781 x 639 ) / 7029

= 781 / 639

= 781

Step2:

LCM(71, 944) = 67024

GCD(71, 944) = ( 71 x 944 ) / 67024

= 71 / 944

= 71

So, Greatest Common Divisor of 781, 639, 944 is 1
