The factors of 20 are 1,2,4,5,10 and 20. Two are odd, four are even.

All of the odd numbers in that range can be factors.

There is no such combination to form an even no. 20 by combing 5 odd nos. as odd+odd=even even +even=evenodd+even=odd even+odd=odd adding 5 odd like

If the sum of two numbers is even, the two numbers are either both even or both odd. A few examples:2 + 4 = 6 (even + even = even)2 + 3 = 5 (even + odd = odd)5 + 2 = 7 (odd + even = odd)7+13 = 20 (odd + odd = even)

There are 40 odd numbers between 20 and 100. Remember that an odd number is every second number. There are 80 numbers between 20 and 100, so there are 40 odd numbers and 40 even numbers.

NO because 5 is a factor of 20 and its odd

No.. All the numbers end with 0,2,4,6,8 are EVEN NUMBERSso 20 is an even number....

1 and 5 are the factors of 20 which are odd.

2 x 2 x 5 = 20 20 is even.

The first 20 odd numbers are: 13579111315171921232527293133353739.

No, all the factors of 20 are not even because 5 which is an odd number is a factor of 20. Well, every number has 1 as its factor, so no counting number can have all even factors.

Two of the factors of 40 are odd. The factors of 40 are: 1, 2, 4, 5, 8, 10, 20, 40

The difference is 2. (23 - 21 = 2).If we are talking about two odd numbers that come right after the number 20 then we mean the two consecutive odd numbers after 20.The difference between any consecutive odd numbers (or between any consecutive even numbers) is always 2.

There are 20 odd numbers in 40.

Ten odd factors.

There are 69 odd numbers between 20 and 158.

4 and 9. Factors of numbers come in pairs which means that every number ought to have an even number of factors. To have an odd number of factors, one factor pair must be a repeated number which means that only square numbers have an odd number of factors. The square numbers less than 20 are 1, 4, 9 & 16 and of these 4 & 9 have 3 factors: 4: 1, 2 & 4 9: 1, 3 & 9

how many odd numbers is there between 20 and 158
