Given numbers are 329, 648, 580, 455

The list of prime factors of all numbers are

Prime factors of 329 are 7 x 47

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

Prime factors of 580 are 2 x 2 x 5 x 29

Prime factors of 455 are 5 x 7 x 13

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

Given numbers are 329, 648, 580, 455

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

Apply this formula for all numbers.

Step1:

LCM(329, 648) = 213192

GCD(329, 648) = ( 329 x 648 ) / 213192

= 329 / 648

= 329

Step2:

LCM(1, 580) = 580

GCD(1, 580) = ( 1 x 580 ) / 580

= 1 / 580

= 1

Step3:

LCM(1, 455) = 455

GCD(1, 455) = ( 1 x 455 ) / 455

= 1 / 455

= 1

So, Greatest Common Divisor of 329, 648, 580, 455 is 1
