Given numbers are 784, 503, 643

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

Apply this formula for all numbers.

Step1:

LCM(784, 503) = 394352

GCD(784, 503) = ( 784 x 503 ) / 394352

= 784 / 503

= 784

Step2:

LCM(1, 643) = 643

GCD(1, 643) = ( 1 x 643 ) / 643

= 1 / 643

= 1

So, Greatest Common Divisor of 784, 503, 643 is 1
