Given numbers are 428, 551, 434, 911

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

Apply this formula for all numbers.

Step1:

LCM(428, 551) = 235828

GCD(428, 551) = ( 428 x 551 ) / 235828

= 428 / 551

= 428

Step2:

LCM(1, 434) = 434

GCD(1, 434) = ( 1 x 434 ) / 434

= 1 / 434

= 1

Step3:

LCM(1, 911) = 911

GCD(1, 911) = ( 1 x 911 ) / 911

= 1 / 911

= 1

So, Greatest Common Divisor of 428, 551, 434, 911 is 1
