Given numbers are 428, 117, 551

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

Apply this formula for all numbers.

Step1:

LCM(428, 117) = 50076

GCD(428, 117) = ( 428 x 117 ) / 50076

= 428 / 117

= 428

Step2:

LCM(1, 551) = 551

GCD(1, 551) = ( 1 x 551 ) / 551

= 1 / 551

= 1

So, Greatest Common Divisor of 428, 117, 551 is 1
