Given numbers are 234, 645, 831, 820

The list of prime factors of all numbers are

Prime factors of 234 are 2 x 3 x 3 x 13

Prime factors of 645 are 3 x 5 x 43

Prime factors of 831 are 3 x 277

Prime factors of 820 are 2 x 2 x 5 x 41

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

Given numbers are 234, 645, 831, 820

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

Apply this formula for all numbers.

Step1:

LCM(234, 645) = 50310

GCD(234, 645) = ( 234 x 645 ) / 50310

= 234 / 645

= 234

Step2:

LCM(3, 831) = 831

GCD(3, 831) = ( 3 x 831 ) / 831

= 3 / 831

= 3

Step3:

LCM(3, 820) = 2460

GCD(3, 820) = ( 3 x 820 ) / 2460

= 3 / 820

= 3

So, Greatest Common Divisor of 234, 645, 831, 820 is 1
