Given numbers are 858, 302, 242, 645

The list of prime factors of all numbers are

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

Prime factors of 302 are 2 x 151

Prime factors of 242 are 2 x 11 x 11

Prime factors of 645 are 3 x 5 x 43

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

Given numbers are 858, 302, 242, 645

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

Apply this formula for all numbers.

Step1:

LCM(858, 302) = 129558

GCD(858, 302) = ( 858 x 302 ) / 129558

= 858 / 302

= 858

Step2:

LCM(2, 242) = 242

GCD(2, 242) = ( 2 x 242 ) / 242

= 2 / 242

= 2

Step3:

LCM(2, 645) = 1290

GCD(2, 645) = ( 2 x 645 ) / 1290

= 2 / 645

= 2

So, Greatest Common Divisor of 858, 302, 242, 645 is 1
