Given numbers are 321, 149, 570, 550

The list of prime factors of all numbers are

Prime factors of 321 are 3 x 107

Prime factors of 149 are 149

Prime factors of 570 are 2 x 3 x 5 x 19

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

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

Given numbers are 321, 149, 570, 550

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

Apply this formula for all numbers.

Step1:

LCM(321, 149) = 47829

GCD(321, 149) = ( 321 x 149 ) / 47829

= 321 / 149

= 321

Step2:

LCM(1, 570) = 570

GCD(1, 570) = ( 1 x 570 ) / 570

= 1 / 570

= 1

Step3:

LCM(1, 550) = 550

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

= 1 / 550

= 1

So, Greatest Common Divisor of 321, 149, 570, 550 is 1
