Given numbers are 409, 423, 821, 227

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

Apply this formula for all numbers.

Step1:

LCM(409, 423) = 173007

GCD(409, 423) = ( 409 x 423 ) / 173007

= 409 / 423

= 409

Step2:

LCM(1, 821) = 821

GCD(1, 821) = ( 1 x 821 ) / 821

= 1 / 821

= 1

Step3:

LCM(1, 227) = 227

GCD(1, 227) = ( 1 x 227 ) / 227

= 1 / 227

= 1

So, Greatest Common Divisor of 409, 423, 821, 227 is 1
