Given numbers are 171, 390, 143, 382

The list of prime factors of all numbers are

Prime factors of 171 are 3 x 3 x 19

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

Prime factors of 143 are 11 x 13

Prime factors of 382 are 2 x 191

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

Given numbers are 171, 390, 143, 382

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

Apply this formula for all numbers.

Step1:

LCM(171, 390) = 22230

GCD(171, 390) = ( 171 x 390 ) / 22230

= 171 / 390

= 171

Step2:

LCM(3, 143) = 429

GCD(3, 143) = ( 3 x 143 ) / 429

= 3 / 143

= 3

Step3:

LCM(1, 382) = 382

GCD(1, 382) = ( 1 x 382 ) / 382

= 1 / 382

= 1

So, Greatest Common Divisor of 171, 390, 143, 382 is 1
