Given numbers are 845, 385, 784, 605

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

Apply this formula for all numbers.

Step1:

LCM(845, 385) = 65065

GCD(845, 385) = ( 845 x 385 ) / 65065

= 845 / 385

= 845

Step2:

LCM(5, 784) = 3920

GCD(5, 784) = ( 5 x 784 ) / 3920

= 5 / 784

= 5

Step3:

LCM(1, 605) = 605

GCD(1, 605) = ( 1 x 605 ) / 605

= 1 / 605

= 1

So, Greatest Common Divisor of 845, 385, 784, 605 is 1
