Given numbers are 247, 830, 257, 752

The list of prime factors of all numbers are

Prime factors of 247 are 13 x 19

Prime factors of 830 are 2 x 5 x 83

Prime factors of 257 are 257

Prime factors of 752 are 2 x 2 x 2 x 2 x 47

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

Given numbers are 247, 830, 257, 752

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

Apply this formula for all numbers.

Step1:

LCM(247, 830) = 205010

GCD(247, 830) = ( 247 x 830 ) / 205010

= 247 / 830

= 247

Step2:

LCM(1, 257) = 257

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

= 1 / 257

= 1

Step3:

LCM(1, 752) = 752

GCD(1, 752) = ( 1 x 752 ) / 752

= 1 / 752

= 1

So, Greatest Common Divisor of 247, 830, 257, 752 is 1
