Given numbers are 621, 344, 378, 330

The list of prime factors of all numbers are

Prime factors of 621 are 3 x 3 x 3 x 23

Prime factors of 344 are 2 x 2 x 2 x 43

Prime factors of 378 are 2 x 3 x 3 x 3 x 7

Prime factors of 330 are 2 x 3 x 5 x 11

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

Given numbers are 621, 344, 378, 330

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

Apply this formula for all numbers.

Step1:

LCM(621, 344) = 213624

GCD(621, 344) = ( 621 x 344 ) / 213624

= 621 / 344

= 621

Step2:

LCM(1, 378) = 378

GCD(1, 378) = ( 1 x 378 ) / 378

= 1 / 378

= 1

Step3:

LCM(1, 330) = 330

GCD(1, 330) = ( 1 x 330 ) / 330

= 1 / 330

= 1

So, Greatest Common Divisor of 621, 344, 378, 330 is 1
