Given numbers are 845, 605, 399, 637

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

Apply this formula for all numbers.

Step1:

LCM(845, 605) = 102245

GCD(845, 605) = ( 845 x 605 ) / 102245

= 845 / 605

= 845

Step2:

LCM(5, 399) = 1995

GCD(5, 399) = ( 5 x 399 ) / 1995

= 5 / 399

= 5

Step3:

LCM(1, 637) = 637

GCD(1, 637) = ( 1 x 637 ) / 637

= 1 / 637

= 1

So, Greatest Common Divisor of 845, 605, 399, 637 is 1
