Given numbers are 610, 312, 705, 257

The list of prime factors of all numbers are

Prime factors of 610 are 2 x 5 x 61

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

Prime factors of 705 are 3 x 5 x 47

Prime factors of 257 are 257

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

Given numbers are 610, 312, 705, 257

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

Apply this formula for all numbers.

Step1:

LCM(610, 312) = 95160

GCD(610, 312) = ( 610 x 312 ) / 95160

= 610 / 312

= 610

Step2:

LCM(2, 705) = 1410

GCD(2, 705) = ( 2 x 705 ) / 1410

= 2 / 705

= 2

Step3:

LCM(1, 257) = 257

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

= 1 / 257

= 1

So, Greatest Common Divisor of 610, 312, 705, 257 is 1
