Given numbers are 845, 441, 361, 247

The list of prime factors of all numbers are

Prime factors of 845 are 5 x 13 x 13

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

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 845, 441, 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(845, 441) = 372645

GCD(845, 441) = ( 845 x 441 ) / 372645

= 845 / 441

= 845

Step2:

LCM(1, 361) = 361

GCD(1, 361) = ( 1 x 361 ) / 361

= 1 / 361

= 1

Step3:

LCM(1, 247) = 247

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

= 1 / 247

= 1

So, Greatest Common Divisor of 845, 441, 361, 247 is 1
