Given numbers are 440, 470, 915, 247

The list of prime factors of all numbers are

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

Prime factors of 470 are 2 x 5 x 47

Prime factors of 915 are 3 x 5 x 61

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 440, 470, 915, 247

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

Apply this formula for all numbers.

Step1:

LCM(440, 470) = 20680

GCD(440, 470) = ( 440 x 470 ) / 20680

= 440 / 470

= 440

Step2:

LCM(10, 915) = 1830

GCD(10, 915) = ( 10 x 915 ) / 1830

= 10 / 915

= 10

Step3:

LCM(5, 247) = 1235

GCD(5, 247) = ( 5 x 247 ) / 1235

= 5 / 247

= 5

So, Greatest Common Divisor of 440, 470, 915, 247 is 1
