100-0 = 100
To have an odd number of factors, the number must be a square. The only squares between 80 and 100 ()inclusive) are 81 and 100 but 81 does not have a factor of 5, and 100 has 9 factors. Thus the problem (as stated) has no solution. The numbers which have a factor of 5 must end in 0 or 5; the only numbers between 80 and 100 (inclusive) which match this criteria are {80, 85, 90, 95, 100}, which have {10, 4, 12, 4, 9} respectively. If you meant 3 PROPER factors (ie all the factors excluding the number itself), then 85 and 95 both have 3 proper factors.
A natural number is any positive number that is not 0. Any natural number multiplied by 100 is 100 times the number, or the original number with two 0's added to the end. For example, 2 times 100 is 200. 100 times 100 is 10,000.
0 is not a composite number. A composite number has two or more positive integer factors. Zero has none.
The mixed number is unnecassary, since 0 < 0.31 < 1. But:Converting 0.31 into a fraction gives 31/100, and 0/1 = 0. Thus, we have:0 31/100 = 31/100
techincally 0 has the most factors. you can multiply any number you want by 0 to get 0 0x101=0 0x100=0 0x99=0 0x98=0 etc... the factors of 100 are limited to only 9 factors. 1x100=100 2x50=100 4x25=100 5x20=100 10x10=100
60,72,84,90 and 96 each have twelve factors.
1
100-0 = 100
60, 72, 84, 90 and 96 are tied for first with 12. 48 and 80 have 10.
360
60, 72, 84, 90 and 96 each have twelve factors.
They all have factors example 0: 0 1:1 2:1, 2 3:1, 3 etc.
Since 7 is a prime, 7*1 = 7, so that the only possibility for a number to have 7 factors is to have only one prime factor to the power of 6, because 7 = 1 + 6. 64 = 26 = 7 factors (6 + 1) (2 is the smallest prime number) Since 36 > 100, then 64 is the only number between 0 and 100 that have 7 factors.
960 has the most factors in that range.
The prime factors of 100 are 2, and 5. The composite factors are 100, 50, 25, 20, 10, and 4. A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 have a different name.
All of the numbers less than 100 (except for -1, 0 and 1) have prime factors. I suspect you left some qualifying information out of your question.
