Given numbers are 105, 645, 213, 233

The list of prime factors of all numbers are

Prime factors of 105 are 3 x 5 x 7

Prime factors of 645 are 3 x 5 x 43

Prime factors of 213 are 3 x 71

Prime factors of 233 are 233

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

Given numbers are 105, 645, 213, 233

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

Apply this formula for all numbers.

Step1:

LCM(105, 645) = 4515

GCD(105, 645) = ( 105 x 645 ) / 4515

= 105 / 645

= 105

Step2:

LCM(15, 213) = 1065

GCD(15, 213) = ( 15 x 213 ) / 1065

= 15 / 213

= 15

Step3:

LCM(3, 233) = 699

GCD(3, 233) = ( 3 x 233 ) / 699

= 3 / 233

= 3

So, Greatest Common Divisor of 105, 645, 213, 233 is 1
