Given numbers are 858, 681, 503, 257

The list of prime factors of all numbers are

Prime factors of 858 are 2 x 3 x 11 x 13

Prime factors of 681 are 3 x 227

Prime factors of 503 are 503

Prime factors of 257 are 257

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

Given numbers are 858, 681, 503, 257

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

Apply this formula for all numbers.

Step1:

LCM(858, 681) = 194766

GCD(858, 681) = ( 858 x 681 ) / 194766

= 858 / 681

= 858

Step2:

LCM(3, 503) = 1509

GCD(3, 503) = ( 3 x 503 ) / 1509

= 3 / 503

= 3

Step3:

LCM(1, 257) = 257

GCD(1, 257) = ( 1 x 257 ) / 257

= 1 / 257

= 1

So, Greatest Common Divisor of 858, 681, 503, 257 is 1
