Given numbers are 421, 770, 859

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

Apply this formula for all numbers.

Step1:

LCM(421, 770) = 324170

GCD(421, 770) = ( 421 x 770 ) / 324170

= 421 / 770

= 421

Step2:

LCM(1, 859) = 859

GCD(1, 859) = ( 1 x 859 ) / 859

= 1 / 859

= 1

So, Greatest Common Divisor of 421, 770, 859 is 1
