Given numbers are 428, 401, 27, 806

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

Apply this formula for all numbers.

Step1:

LCM(428, 401) = 171628

GCD(428, 401) = ( 428 x 401 ) / 171628

= 428 / 401

= 428

Step2:

LCM(1, 27) = 27

GCD(1, 27) = ( 1 x 27 ) / 27

= 1 / 27

= 1

Step3:

LCM(1, 806) = 806

GCD(1, 806) = ( 1 x 806 ) / 806

= 1 / 806

= 1

So, Greatest Common Divisor of 428, 401, 27, 806 is 1
