Determine smallest divisor of an integer

WebJan 20, 2024 · Example: How many divisors are there of the number 12? 12 = 2^2 x 3 The number 2 can be chosen 0 times, 1 time, 2 times = 3 ways. The number 3 can be chosen 0 times, 1 time = 2 ways. Putting these results together we have 3 x 2 = 6 ways of finding factors of 12. This is the same example we saw before.

WebThe solution for 3 needs to have a factor of 3, but the solution for 2 has no factor of 3. So the solution for 3 is 2 x 3. The solution for 4 needs two factors of 2. The solution for 3 has only one factor of 2, so we add an additional factor of two: 2 x 3 x 2. The solution for 5 needs a factor of 5, but we don't have one in the solution for 4. WebAug 16, 2024 · Notice however that the statement 2 ∣ 18 is related to the fact that 18 / 2 is a whole number. Definition 11.4.1: Greatest Common Divisor.
