Answer:
5
Step-by-step explanation:
To get the Greates Common Factor (GCF) of 225 and 415 we need to factor each value first and then we choose all the copies of factors and multiply them:
225: 3 3 5 5
415: 5 83
GCF: 5
The Greates Common Factor (GCF) is: 5
The factors of 225 are: 1, 3, 5, 9, 15, 25, 45, 75, 225
The factors of 415 are: 1, 5, 83, 415
Then the greatest common factor is 5.
