Given numbers are 903, 678, 361, 247

The list of prime factors of all numbers are

Prime factors of 903 are 3 x 7 x 43

Prime factors of 678 are 2 x 3 x 113

Prime factors of 361 are 19 x 19

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 903, 678, 361, 247

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

Apply this formula for all numbers.

Step1:

LCM(903, 678) = 204078

GCD(903, 678) = ( 903 x 678 ) / 204078

= 903 / 678

= 903

Step2:

LCM(3, 361) = 1083

GCD(3, 361) = ( 3 x 361 ) / 1083

= 3 / 361

= 3

Step3:

LCM(1, 247) = 247

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

= 1 / 247

= 1

So, Greatest Common Divisor of 903, 678, 361, 247 is 1
