Given numbers are 645, 306, 872, 236

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 306 are 2 x 3 x 3 x 17

Prime factors of 872 are 2 x 2 x 2 x 109

Prime factors of 236 are 2 x 2 x 59

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

Given numbers are 645, 306, 872, 236

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

Apply this formula for all numbers.

Step1:

LCM(645, 306) = 65790

GCD(645, 306) = ( 645 x 306 ) / 65790

= 645 / 306

= 645

Step2:

LCM(3, 872) = 2616

GCD(3, 872) = ( 3 x 872 ) / 2616

= 3 / 872

= 3

Step3:

LCM(1, 236) = 236

GCD(1, 236) = ( 1 x 236 ) / 236

= 1 / 236

= 1

So, Greatest Common Divisor of 645, 306, 872, 236 is 1
