Given numbers are 401, 778, 805

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

Apply this formula for all numbers.

Step1:

LCM(401, 778) = 311978

GCD(401, 778) = ( 401 x 778 ) / 311978

= 401 / 778

= 401

Step2:

LCM(1, 805) = 805

GCD(1, 805) = ( 1 x 805 ) / 805

= 1 / 805

= 1

So, Greatest Common Divisor of 401, 778, 805 is 1
