Given numbers are 231, 777, 518, 487

The list of prime factors of all numbers are

Prime factors of 231 are 3 x 7 x 11

Prime factors of 777 are 3 x 7 x 37

Prime factors of 518 are 2 x 7 x 37

Prime factors of 487 are 487

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

Given numbers are 231, 777, 518, 487

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

Apply this formula for all numbers.

Step1:

LCM(231, 777) = 8547

GCD(231, 777) = ( 231 x 777 ) / 8547

= 231 / 777

= 231

Step2:

LCM(21, 518) = 1554

GCD(21, 518) = ( 21 x 518 ) / 1554

= 21 / 518

= 21

Step3:

LCM(7, 487) = 3409

GCD(7, 487) = ( 7 x 487 ) / 3409

= 7 / 487

= 7

So, Greatest Common Divisor of 231, 777, 518, 487 is 1
