Given numbers are 747, 660, 421, 323

The list of prime factors of all numbers are

Prime factors of 747 are 3 x 3 x 83

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 421 are 421

Prime factors of 323 are 17 x 19

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

Given numbers are 747, 660, 421, 323

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

Apply this formula for all numbers.

Step1:

LCM(747, 660) = 164340

GCD(747, 660) = ( 747 x 660 ) / 164340

= 747 / 660

= 747

Step2:

LCM(3, 421) = 1263

GCD(3, 421) = ( 3 x 421 ) / 1263

= 3 / 421

= 3

Step3:

LCM(1, 323) = 323

GCD(1, 323) = ( 1 x 323 ) / 323

= 1 / 323

= 1

So, Greatest Common Divisor of 747, 660, 421, 323 is 1
