Given numbers are 845, 858, 412, 221

The list of prime factors of all numbers are

Prime factors of 845 are 5 x 13 x 13

Prime factors of 858 are 2 x 3 x 11 x 13

Prime factors of 412 are 2 x 2 x 103

Prime factors of 221 are 13 x 17

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 845, 858, 412, 221

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

Apply this formula for all numbers.

Step1:

LCM(845, 858) = 55770

GCD(845, 858) = ( 845 x 858 ) / 55770

= 845 / 858

= 845

Step2:

LCM(13, 412) = 5356

GCD(13, 412) = ( 13 x 412 ) / 5356

= 13 / 412

= 13

Step3:

LCM(1, 221) = 221

GCD(1, 221) = ( 1 x 221 ) / 221

= 1 / 221

= 1

So, Greatest Common Divisor of 845, 858, 412, 221 is 1
