Given numbers are 478, 910, 491, 247

The list of prime factors of all numbers are

Prime factors of 478 are 2 x 239

Prime factors of 910 are 2 x 5 x 7 x 13

Prime factors of 491 are 491

Prime factors of 247 are 13 x 19

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

Given numbers are 478, 910, 491, 247

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

Apply this formula for all numbers.

Step1:

LCM(478, 910) = 217490

GCD(478, 910) = ( 478 x 910 ) / 217490

= 478 / 910

= 478

Step2:

LCM(2, 491) = 982

GCD(2, 491) = ( 2 x 491 ) / 982

= 2 / 491

= 2

Step3:

LCM(1, 247) = 247

GCD(1, 247) = ( 1 x 247 ) / 247

= 1 / 247

= 1

So, Greatest Common Divisor of 478, 910, 491, 247 is 1
