Given numbers are 245, 615, 345, 347

The list of prime factors of all numbers are

Prime factors of 245 are 5 x 7 x 7

Prime factors of 615 are 3 x 5 x 41

Prime factors of 345 are 3 x 5 x 23

Prime factors of 347 are 347

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

Given numbers are 245, 615, 345, 347

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

Apply this formula for all numbers.

Step1:

LCM(245, 615) = 30135

GCD(245, 615) = ( 245 x 615 ) / 30135

= 245 / 615

= 245

Step2:

LCM(5, 345) = 345

GCD(5, 345) = ( 5 x 345 ) / 345

= 5 / 345

= 5

Step3:

LCM(5, 347) = 1735

GCD(5, 347) = ( 5 x 347 ) / 1735

= 5 / 347

= 5

So, Greatest Common Divisor of 245, 615, 345, 347 is 1
