Given numbers are 781, 962, 438

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

Apply this formula for all numbers.

Step1:

LCM(781, 962) = 751322

GCD(781, 962) = ( 781 x 962 ) / 751322

= 781 / 962

= 781

Step2:

LCM(1, 438) = 438

GCD(1, 438) = ( 1 x 438 ) / 438

= 1 / 438

= 1

So, Greatest Common Divisor of 781, 962, 438 is 1
