Given numbers are 648, 332, 261, 330

The list of prime factors of all numbers are

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 332 are 2 x 2 x 83

Prime factors of 261 are 3 x 3 x 29

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 648, 332, 261, 330

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

Apply this formula for all numbers.

Step1:

LCM(648, 332) = 53784

GCD(648, 332) = ( 648 x 332 ) / 53784

= 648 / 332

= 648

Step2:

LCM(4, 261) = 1044

GCD(4, 261) = ( 4 x 261 ) / 1044

= 4 / 261

= 4

Step3:

LCM(1, 330) = 330

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

= 1 / 330

= 1

So, Greatest Common Divisor of 648, 332, 261, 330 is 1
