It doesn't; they have the same number of factors.
Two factors of 40 are 20 and 2. There are no more factors of 2, but factors of 20 include 5 and 4. There are no more factors of 5 but 4 factors of 4 include 2 and 2. So, the factors of 40 are 2, 5, 2, 2 This simplifies to make 2^3 * 5 Hope that helped :)
50 with more than 2 factors:1 x 2 x 252 x 5 x 5
2 x 5 x 5 = 50
Factors: (will fill in later).Prime Factors: 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 3, 5, 5, 5, 5, 5, 5, 5, 5, 5
The factors of 5 are 1 and 5. The factors of 2 are 1 and 2.
The factors of 2 are:1, 2The factors of 5 are:1, 5
2 x 5 x 5 = 50
Factors of 90: 2*3^2*5 Factors of 100: 2^2*5^2
Do you mean, what is it evenly divisible by? You can answer questions like these by finding the factors of the number and multiplying different factors: 215 ends in 5, so we know 5 is one if its factors. Divide by 5: we're left with 43. 43 is a prime number, it can't be factored any more. 215 is only divisible by 5 and 43. As a better example of how this technique works, consider 100. 100's factors are 5, 5, 2, and 2. By multiplying together different factors, we can discover that 100 is not only divisible directly by its factors 5 and 2, but also by 5*5, 2*2, 5*2, 5*5*2 and 2*2*5.
The positive integer factors of 20 are: 1 2 4 5 10 20 The positive integer factors of 30 are: 1 2 3 5 6 10 15 30 Therefore, out of the two numbers, 30 has more factors.
25 factors to [5 5] 125 factors to [5 5 5] 200 factors to [2 2 2 5 5] Common factors are [5 5] so GCF = 25 25
5 and 9 come to mind (there are more of course)
