Given numbers are 645, 178, 810, 283

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 178 are 2 x 89

Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5

Prime factors of 283 are 283

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

Given numbers are 645, 178, 810, 283

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

Apply this formula for all numbers.

Step1:

LCM(645, 178) = 114810

GCD(645, 178) = ( 645 x 178 ) / 114810

= 645 / 178

= 645

Step2:

LCM(1, 810) = 810

GCD(1, 810) = ( 1 x 810 ) / 810

= 1 / 810

= 1

Step3:

LCM(1, 283) = 283

GCD(1, 283) = ( 1 x 283 ) / 283

= 1 / 283

= 1

So, Greatest Common Divisor of 645, 178, 810, 283 is 1
