Factors of 99: 1, 3, 9, 11, 33, 99. Factors of 100: 1, 2, 4, 5, 10, 20, 25, 50, 100.
What has only 3 factors?
As it turns out, the only positive integers with exactly three factors are the squares of primes. For instance, the factors of 9 are 1, 3, and 9, and the factors of 49 are 1, 7, and 49. If you find all of the factors of a non-square, you can “pair off” the factors.
What is the factor tree for 100?
The number 100 is a composite number because 100 can be divided by 1, by itself and at least by 2 and 5. So, it is possible to draw its prime tree. The prime factorization of 100 = 22•52.
What are the factors of 80?
The factors of 80 are 1, 2, 4, 5, 8, 10, 16, 20, 40, and 80. Hence, it is a composite number.
How many factors does 12 have?
six factors
More mathematical background So, 12 has six factors — 1, 2, 3, 4, 6, and 12 — but only two of them (2 and 3) are prime, so it has only two prime factors. The prime factorization of a number is a factorization — a way of expressing that number as a product — consisting only of primes.
How many factors are in the factor of 100?
