Given numbers are 231, 343, 855, 509

The list of prime factors of all numbers are

Prime factors of 231 are 3 x 7 x 11

Prime factors of 343 are 7 x 7 x 7

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 509 are 509

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

Given numbers are 231, 343, 855, 509

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

Apply this formula for all numbers.

Step1:

LCM(231, 343) = 11319

GCD(231, 343) = ( 231 x 343 ) / 11319

= 231 / 343

= 231

Step2:

LCM(7, 855) = 5985

GCD(7, 855) = ( 7 x 855 ) / 5985

= 7 / 855

= 7

Step3:

LCM(1, 509) = 509

GCD(1, 509) = ( 1 x 509 ) / 509

= 1 / 509

= 1

So, Greatest Common Divisor of 231, 343, 855, 509 is 1
