Given numbers are 405, 420, 897, 111

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

Apply this formula for all numbers.

Step1:

LCM(405, 420) = 11340

GCD(405, 420) = ( 405 x 420 ) / 11340

= 405 / 420

= 405

Step2:

LCM(15, 897) = 4485

GCD(15, 897) = ( 15 x 897 ) / 4485

= 15 / 897

= 15

Step3:

LCM(3, 111) = 111

GCD(3, 111) = ( 3 x 111 ) / 111

= 3 / 111

= 3

So, Greatest Common Divisor of 405, 420, 897, 111 is 3
