Given numbers are 405, 891, 181, 359

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

Apply this formula for all numbers.

Step1:

LCM(405, 891) = 4455

GCD(405, 891) = ( 405 x 891 ) / 4455

= 405 / 891

= 405

Step2:

LCM(81, 181) = 14661

GCD(81, 181) = ( 81 x 181 ) / 14661

= 81 / 181

= 81

Step3:

LCM(1, 359) = 359

GCD(1, 359) = ( 1 x 359 ) / 359

= 1 / 359

= 1

So, Greatest Common Divisor of 405, 891, 181, 359 is 1
