Given numbers are 390, 180, 580, 181

The list of prime factors of all numbers are

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 180 are 2 x 2 x 3 x 3 x 5

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

Prime factors of 181 are 181

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

Given numbers are 390, 180, 580, 181

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

Apply this formula for all numbers.

Step1:

LCM(390, 180) = 2340

GCD(390, 180) = ( 390 x 180 ) / 2340

= 390 / 180

= 390

Step2:

LCM(30, 580) = 1740

GCD(30, 580) = ( 30 x 580 ) / 1740

= 30 / 580

= 30

Step3:

LCM(10, 181) = 1810

GCD(10, 181) = ( 10 x 181 ) / 1810

= 10 / 181

= 10

So, Greatest Common Divisor of 390, 180, 580, 181 is 1
