Given numbers are 421, 401, 784

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

Apply this formula for all numbers.

Step1:

LCM(421, 401) = 168821

GCD(421, 401) = ( 421 x 401 ) / 168821

= 421 / 401

= 421

Step2:

LCM(1, 784) = 784

GCD(1, 784) = ( 1 x 784 ) / 784

= 1 / 784

= 1

So, Greatest Common Divisor of 421, 401, 784 is 1
