Given numbers are 315, 978, 441, 247

The list of prime factors of all numbers are

Prime factors of 315 are 3 x 3 x 5 x 7

Prime factors of 978 are 2 x 3 x 163

Prime factors of 441 are 3 x 3 x 7 x 7

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 315, 978, 441, 247

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

Apply this formula for all numbers.

Step1:

LCM(315, 978) = 102690

GCD(315, 978) = ( 315 x 978 ) / 102690

= 315 / 978

= 315

Step2:

LCM(3, 441) = 441

GCD(3, 441) = ( 3 x 441 ) / 441

= 3 / 441

= 3

Step3:

LCM(3, 247) = 741

GCD(3, 247) = ( 3 x 247 ) / 741

= 3 / 247

= 3

So, Greatest Common Divisor of 315, 978, 441, 247 is 1
