Given numbers are 328, 539, 550, 644

The list of prime factors of all numbers are

Prime factors of 328 are 2 x 2 x 2 x 41

Prime factors of 539 are 7 x 7 x 11

Prime factors of 550 are 2 x 5 x 5 x 11

Prime factors of 644 are 2 x 2 x 7 x 23

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

Given numbers are 328, 539, 550, 644

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

Apply this formula for all numbers.

Step1:

LCM(328, 539) = 176792

GCD(328, 539) = ( 328 x 539 ) / 176792

= 328 / 539

= 328

Step2:

LCM(1, 550) = 550

GCD(1, 550) = ( 1 x 550 ) / 550

= 1 / 550

= 1

Step3:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 328, 539, 550, 644 is 1
