Given numbers are 845, 169, 663, 858

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

Apply this formula for all numbers.

Step1:

LCM(845, 169) = 845

GCD(845, 169) = ( 845 x 169 ) / 845

= 845 / 169

= 845

Step2:

LCM(169, 663) = 8619

GCD(169, 663) = ( 169 x 663 ) / 8619

= 169 / 663

= 169

Step3:

LCM(13, 858) = 858

GCD(13, 858) = ( 13 x 858 ) / 858

= 13 / 858

= 13

So, Greatest Common Divisor of 845, 169, 663, 858 is 13
