Given numbers are 428, 409, 928

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

Apply this formula for all numbers.

Step1:

LCM(428, 409) = 175052

GCD(428, 409) = ( 428 x 409 ) / 175052

= 428 / 409

= 428

Step2:

LCM(1, 928) = 928

GCD(1, 928) = ( 1 x 928 ) / 928

= 1 / 928

= 1

So, Greatest Common Divisor of 428, 409, 928 is 1
