Given numbers are 247, 936, 245, 388

The list of prime factors of all numbers are

Prime factors of 247 are 13 x 19

Prime factors of 936 are 2 x 2 x 2 x 3 x 3 x 13

Prime factors of 245 are 5 x 7 x 7

Prime factors of 388 are 2 x 2 x 97

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

Given numbers are 247, 936, 245, 388

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

Apply this formula for all numbers.

Step1:

LCM(247, 936) = 17784

GCD(247, 936) = ( 247 x 936 ) / 17784

= 247 / 936

= 247

Step2:

LCM(13, 245) = 3185

GCD(13, 245) = ( 13 x 245 ) / 3185

= 13 / 245

= 13

Step3:

LCM(1, 388) = 388

GCD(1, 388) = ( 1 x 388 ) / 388

= 1 / 388

= 1

So, Greatest Common Divisor of 247, 936, 245, 388 is 1
