Given numbers are 259, 338, 312, 840

The list of prime factors of all numbers are

Prime factors of 259 are 7 x 37

Prime factors of 338 are 2 x 13 x 13

Prime factors of 312 are 2 x 2 x 2 x 3 x 13

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

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

Given numbers are 259, 338, 312, 840

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

Apply this formula for all numbers.

Step1:

LCM(259, 338) = 87542

GCD(259, 338) = ( 259 x 338 ) / 87542

= 259 / 338

= 259

Step2:

LCM(1, 312) = 312

GCD(1, 312) = ( 1 x 312 ) / 312

= 1 / 312

= 1

Step3:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

So, Greatest Common Divisor of 259, 338, 312, 840 is 1
