If you mean prime number, it is a number which can only be divided by 1 and itself. For example: 2 because only 1 and 2 are the factors of 2 5 because only 1 and 5 are the factors of 5
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.
3 5/8 - 2 1/4 = 1 3/8
Answer #1: no==================Answer #2:If you honestly don't know, then here's a little tip that will blow your mind:-- If a number has 5 as one of its factors, then the number ends with a 5 or a zero.-- If a number ends with a 5 or a zero, then 5 is one of its factors.-- If a number doesn't end with a 5 or a zero, then 5 is not one of its factors.
The factors of 16 are 1, 2, 4, 8, and 16.
15, 30,45, 60, 75, 90, 105,......................... any number that is a multiple of 15
2 and 5 are factors of 10
The prime factors are: 2 x 2 x 5
sixteen-fifths as a mixed number is 3and 1/5
As a product of its oprime factors: 2*5*7 = 70
2
Sorry. There are no numbers between 1 and 2 that have 5 factors.
It doesn't; they have the same number of factors.
5 is a prime number so therefore it has only 2 factors which are itself and one
30 is the first number that has factors of 2, 3, and 5.
2 cannot be a factor as 215 is not an even number. Factors are 5 x 43
30 and all multiples of 30 have 2, 3, and 5 among their factors.
