Given numbers are 247, 496, 378, 440

The list of prime factors of all numbers are

Prime factors of 247 are 13 x 19

Prime factors of 496 are 2 x 2 x 2 x 2 x 31

Prime factors of 378 are 2 x 3 x 3 x 3 x 7

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

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

Given numbers are 247, 496, 378, 440

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

Apply this formula for all numbers.

Step1:

LCM(247, 496) = 122512

GCD(247, 496) = ( 247 x 496 ) / 122512

= 247 / 496

= 247

Step2:

LCM(1, 378) = 378

GCD(1, 378) = ( 1 x 378 ) / 378

= 1 / 378

= 1

Step3:

LCM(1, 440) = 440

GCD(1, 440) = ( 1 x 440 ) / 440

= 1 / 440

= 1

So, Greatest Common Divisor of 247, 496, 378, 440 is 1
