Given numbers are 740, 645, 423, 321

The list of prime factors of all numbers are

Prime factors of 740 are 2 x 2 x 5 x 37

Prime factors of 645 are 3 x 5 x 43

Prime factors of 423 are 3 x 3 x 47

Prime factors of 321 are 3 x 107

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

Given numbers are 740, 645, 423, 321

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

Apply this formula for all numbers.

Step1:

LCM(740, 645) = 95460

GCD(740, 645) = ( 740 x 645 ) / 95460

= 740 / 645

= 740

Step2:

LCM(5, 423) = 2115

GCD(5, 423) = ( 5 x 423 ) / 2115

= 5 / 423

= 5

Step3:

LCM(1, 321) = 321

GCD(1, 321) = ( 1 x 321 ) / 321

= 1 / 321

= 1

So, Greatest Common Divisor of 740, 645, 423, 321 is 1
