There are 44 positive integers less than 2,010 that have an odd number of factors.
Because 44 has more than two factors
44 is a composite number; it has factors other than 1 and itself. It is not a prime number. The 6 factors of 44 are 1, 2, 4, 11, 22, and 44. Of these, 2 and 11 are prime.

To find the prime factors of a number, start with any two factors of the numbers and keep factoring the composite factors until they are all prime. 44 2 x 22 2 x 2 x 11 = 44
Three factors in common.
Factors are numbers you can multiply together to get another number. 44: 1, 2, 4, 11, 22, 44
44 has six factors: 1, 2, 4, 11, 22, 44.
