Given numbers are 405, 156, 211, 919

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

Apply this formula for all numbers.

Step1:

LCM(405, 156) = 21060

GCD(405, 156) = ( 405 x 156 ) / 21060

= 405 / 156

= 405

Step2:

LCM(3, 211) = 633

GCD(3, 211) = ( 3 x 211 ) / 633

= 3 / 211

= 3

Step3:

LCM(1, 919) = 919

GCD(1, 919) = ( 1 x 919 ) / 919

= 1 / 919

= 1

So, Greatest Common Divisor of 405, 156, 211, 919 is 1
