Given numbers are 455, 429, 549, 111

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

Apply this formula for all numbers.

Step1:

LCM(455, 429) = 15015

GCD(455, 429) = ( 455 x 429 ) / 15015

= 455 / 429

= 455

Step2:

LCM(13, 549) = 7137

GCD(13, 549) = ( 13 x 549 ) / 7137

= 13 / 549

= 13

Step3:

LCM(1, 111) = 111

GCD(1, 111) = ( 1 x 111 ) / 111

= 1 / 111

= 1

So, Greatest Common Divisor of 455, 429, 549, 111 is 1
