Given numbers are 401, 406, 784

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

Apply this formula for all numbers.

Step1:

LCM(401, 406) = 162806

GCD(401, 406) = ( 401 x 406 ) / 162806

= 401 / 406

= 401

Step2:

LCM(1, 784) = 784

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

= 1 / 784

= 1

So, Greatest Common Divisor of 401, 406, 784 is 1
