Given numbers are 297, 858, 789, 845

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

Apply this formula for all numbers.

Step1:

LCM(297, 858) = 7722

GCD(297, 858) = ( 297 x 858 ) / 7722

= 297 / 858

= 297

Step2:

LCM(33, 789) = 8679

GCD(33, 789) = ( 33 x 789 ) / 8679

= 33 / 789

= 33

Step3:

LCM(3, 845) = 2535

GCD(3, 845) = ( 3 x 845 ) / 2535

= 3 / 845

= 3

So, Greatest Common Divisor of 297, 858, 789, 845 is 1
