Given numbers are 428, 438, 917, 605

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

Apply this formula for all numbers.

Step1:

LCM(428, 438) = 93732

GCD(428, 438) = ( 428 x 438 ) / 93732

= 428 / 438

= 428

Step2:

LCM(2, 917) = 1834

GCD(2, 917) = ( 2 x 917 ) / 1834

= 2 / 917

= 2

Step3:

LCM(1, 605) = 605

GCD(1, 605) = ( 1 x 605 ) / 605

= 1 / 605

= 1

So, Greatest Common Divisor of 428, 438, 917, 605 is 1
