There is no meaningful way to talk about factors of rational numbers. A rational can be divided by any other non-zero rational to give a rational and, in that sense, every rational is a factor.
The factors of 4 are 1, 2, 4 The factors of 15 are 1, 3, 5, 15
The common factor of 4 and 15 is 1. They are coprime, as they share no factor other than 1.The factors of 4 and 1, 2, and 4.The factors of 15 are 1, 3, 5, and 15.
4/5 - 8/15 = 12/15 - 8/15 = 4/15
The factors of 15 are: 1, 3, 5, 15 The factors of 16 are: 1, 2, 4, 8, 16
1/3 -4/15 is the same as 5/15 -4/15 and the answer is 1/15
The factors of 3 are: 1 and 3The factors of 4 are: 1, 2, and 4None of the factors of 3 or 4 are between 15 and 45.
4/15
12 over 15.
4/15, 4 over 15.
The factors of 12 are 1, 2, 3, 4, 6, and 12 The factors of 15 are 1, 3, 5, and 15
4/15 = 4 ÷ 15 = 0.266667
15 only has 4. 1,3,5 and 15
