Given numbers are 373, 840, 230, 645

The list of prime factors of all numbers are

Prime factors of 373 are 373

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 230 are 2 x 5 x 23

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 373, 840, 230, 645

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

Apply this formula for all numbers.

Step1:

LCM(373, 840) = 313320

GCD(373, 840) = ( 373 x 840 ) / 313320

= 373 / 840

= 373

Step2:

LCM(1, 230) = 230

GCD(1, 230) = ( 1 x 230 ) / 230

= 1 / 230

= 1

Step3:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 373, 840, 230, 645 is 1
