Given numbers are 425, 779, 861

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

Apply this formula for all numbers.

Step1:

LCM(425, 779) = 331075

GCD(425, 779) = ( 425 x 779 ) / 331075

= 425 / 779

= 425

Step2:

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

= 1 / 861

= 1

So, Greatest Common Divisor of 425, 779, 861 is 1
