10=5*2
9= 3*3
8= 2*2*2
7= 7
6= 3*2
5= 5
4= 2*2
3= 3
2= 2
1= 1
We need a product that include all of the combinations in the right column.
Starting from the top:
10 gives us: 5*2
9 gives us: 3*3
8 gives us: 2*2 (we already have the third 2)
7 gives us: 7
6 gives us: nothing (we already have both a 2 and a 3)
5 gives us: nothing
4 gives us: nothing
3 gives us: nothing
2 gives us: nothing
1 gives us: 1 So: 5*2*3*3*2*2*7*1=2520. There is no number between 1 and 2000 that fits.
48 has the most factors; it has 10 factors: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48
The number 10 can be the product of 2 and 5, 1 and 10. This means that 10 has 4 factors. :]
11
A multiple is found by multiplying the number. Whereas a factor is what the number can be divided by. For example - multiples of 10 are; 10, 20, 30, 40, ... Factors of 10 are; 1, 2, 5, 10
Four
A number that has exactly an odd number of factors is a power of another number. A number between 10 and 30 that is a power is 16. It is 24 (as well as 42) and its factors are 1, 2, 4, 8, and 16.
48 has 10 factors.
12
2555
5, 10, 15 and 20 have five as a factor. The number 16 has five factors.
3 x 4 = 12
16, with factors 1, 2, 4, 8 and 16.
There are no factors of 10 between 20 and 100.
48 has the most factors; it has 10 factors: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48
6, 8, 10, 14, 15
Any number between 30 and 40 can be a factor. The common factors of 30 and 40 are 1, 2, 5 and 10.
it is an even number it is composite number it is a square number it is a number between 10 and 100 it has factors and multiples and it has a prime factorization.................................
