What are two examples of a type of number that has an odd number factor?
There are square numbers (numbers which are a square of an integer), such as 4. It's factors, listed are 1, 2, and 4. All square numbers have an odd number of factors. Then there's 1, which has only 1 factor: 1. All other numbers have an even number of factors. Prime numbers will have only 2 factors (2 is even).
What is special about the number of factors for square numbers?
Square numbers have an odd number of factors, all others have an even number. In this context, primes can either be considered as having 0 factors (an even number) or 2 factors - 1 and itself, again, an even number.
How many 2 digit numbers have even no of factors?
Total number of 2-digit numbers = (99 - 9) = 90 of themEvery number that isn't a perfect square has an even number of factors.2-digit numbers that are perfect squares: 16, 25, 36, 49, 64, and 81 = 6 of themRemaining 2-digit numbers = (99 - 6) = 93 .
Square numbers prime or composite?
All square numbers greater than 1 are composite.
What is the square root of 2594?
2594 is the product of the prime numbers 2 and 1297. If you were looking for the decimal form, it would be 50.931326312987373449092058406634. Otherwise, you would write it as the square root of 2594 as it has no square factors.
How many square numbers are factors of 1600?
To find the square numbers that are factors of 1600, we first need to find the prime factorization of 1600, which is 2^6 * 5^2. A square number is a number that can be expressed as the square of an integer. In this case, the factors of 1600 that are square numbers are 1, 4, 16, 25, 64, 100, and 400. Therefore, there are 7 square numbers that are factors of 1600.
What types of numbers has an odd number of factors give examples?
Square numbers have odd numbers of factors.

What is the smallest square numbers that has 2 and 5 as factors?
It is: 100
What are the square numbers that are factors of 18?
The factors of 18 are 1, 2, 3, 6, 9, and 18. The only square number of those numbers is 9.
Do all square numbers have exactly 3 factors?
No. 81=9*9=3*27=1*81 81 has 5 factors and is a square number. 36=6*6=3*12=1*36=2*18=4*9 36 has 9 factors and is a square number. This doesn't mean that no square numbers have exactly 3 factors though, because: 9=3*3=1*9 9 has 3 factors and is a square number. 4=2*2=1*4 4 has 3 factors and is a square number. All square numbers have an odd number of factors though (because they have a whole number which multiplies by itself to get the number). Factors are whole numbers only, and not decimals. Hope this helps :)
What are all factors of 36 that are also square numbers?
Factors of 36: 1, 2, 3, 4, 6, 9, 12, 18, 36 1 = 1^2 4 = 2^2 9 = 3^2 36 = 6^2 Therefore, the factors of 36 that are also square numbers are 1, 4, 9, and 36.

What are numbers that have 2 factors?
Numbers that have only 2 factors are prime numbers
How many factors do perfect square numbers have?
It depends what square number you're looking at. The square number 25 has only three factors (1, 5 and 25) but the square number 16 has 5 (1, 2, 4, 8 and 16.) A key point is that the factors don't pair up. There is always one middle factor that is the square root of the number and so cannot pair with any other factor. This means that all square numbers have an odd number of factors, while other numbers have an even number of factors.
Which of these numbers has an odd number of factors 12 25 37 42 64 69?
16 has an odd number of factors; its factors are 1, 2, 4, 8, and 16
What are three factors that has the numbers 2 4 and 8?
Factors don't have numbers. Numbers have factors. Numbers that have the factors 2, 4 and 8 are 8 and all of its multiples.
