The least common factor of any set of positive integers is 1.
To get the Greates Common Factor (GCF) of 30 and 105 we need to factor each value first and then we choose all the copies of factors and multiply them:30: 2 3 5 105: 3 5 7 GCF: 3 5The Greates Common Factor (GCF) is: 3 x 5 = 15
The greatest common factor of 30 and 105 is 15.
