Given numbers are 861, 257, 534, 517

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 257 are 257

Prime factors of 534 are 2 x 3 x 89

Prime factors of 517 are 11 x 47

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

Given numbers are 861, 257, 534, 517

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

Apply this formula for all numbers.

Step1:

LCM(861, 257) = 221277

GCD(861, 257) = ( 861 x 257 ) / 221277

= 861 / 257

= 861

Step2:

LCM(1, 534) = 534

GCD(1, 534) = ( 1 x 534 ) / 534

= 1 / 534

= 1

Step3:

LCM(1, 517) = 517

GCD(1, 517) = ( 1 x 517 ) / 517

= 1 / 517

= 1

So, Greatest Common Divisor of 861, 257, 534, 517 is 1
