Given numbers are 721, 556, 785

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

Apply this formula for all numbers.

Step1:

LCM(721, 556) = 400876

GCD(721, 556) = ( 721 x 556 ) / 400876

= 721 / 556

= 721

Step2:

LCM(1, 785) = 785

GCD(1, 785) = ( 1 x 785 ) / 785

= 1 / 785

= 1

So, Greatest Common Divisor of 721, 556, 785 is 1
