Given numbers are 247, 458, 217, 860

The list of prime factors of all numbers are

Prime factors of 247 are 13 x 19

Prime factors of 458 are 2 x 229

Prime factors of 217 are 7 x 31

Prime factors of 860 are 2 x 2 x 5 x 43

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

Given numbers are 247, 458, 217, 860

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

Apply this formula for all numbers.

Step1:

LCM(247, 458) = 113126

GCD(247, 458) = ( 247 x 458 ) / 113126

= 247 / 458

= 247

Step2:

LCM(1, 217) = 217

GCD(1, 217) = ( 1 x 217 ) / 217

= 1 / 217

= 1

Step3:

LCM(1, 860) = 860

GCD(1, 860) = ( 1 x 860 ) / 860

= 1 / 860

= 1

So, Greatest Common Divisor of 247, 458, 217, 860 is 1
