Given numbers are 845, 808, 56, 409

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

Apply this formula for all numbers.

Step1:

LCM(845, 808) = 682760

GCD(845, 808) = ( 845 x 808 ) / 682760

= 845 / 808

= 845

Step2:

LCM(1, 56) = 56

GCD(1, 56) = ( 1 x 56 ) / 56

= 1 / 56

= 1

Step3:

LCM(1, 409) = 409

GCD(1, 409) = ( 1 x 409 ) / 409

= 1 / 409

= 1

So, Greatest Common Divisor of 845, 808, 56, 409 is 1
