Given numbers are 318, 890, 257, 770

The list of prime factors of all numbers are

Prime factors of 318 are 2 x 3 x 53

Prime factors of 890 are 2 x 5 x 89

Prime factors of 257 are 257

Prime factors of 770 are 2 x 5 x 7 x 11

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

Given numbers are 318, 890, 257, 770

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

Apply this formula for all numbers.

Step1:

LCM(318, 890) = 141510

GCD(318, 890) = ( 318 x 890 ) / 141510

= 318 / 890

= 318

Step2:

LCM(2, 257) = 514

GCD(2, 257) = ( 2 x 257 ) / 514

= 2 / 257

= 2

Step3:

LCM(1, 770) = 770

GCD(1, 770) = ( 1 x 770 ) / 770

= 1 / 770

= 1

So, Greatest Common Divisor of 318, 890, 257, 770 is 1
