Why are there only odd factors in 135?
whereas, the prime factorization of 135 does not contain the prime factor 2, so 135 has no even factors, all factors are odd. Thus, the number of odd factors depends on the prime factor 2 of prime factorization of any number. It means only an even number can have an even and an odd factors whereas an odd number has only odd factors.
How many odd numbers are there between 1 to 100?
Example 4: How many odd numbers are there between 1 to 100? Solution: There are 50 odd numbers and 50 even numbers between 1 to 100. Number of odd numbers = 100/2 = 50
