What are all the odd factors of 20?
1 and 5 are the factors of 20 which are odd.
What is the sum of all factors of 20?
Factors of 20 are 1, 2, 4, 5, 10 and 20. And their sum is 1 + 2 + 4 + 5 + 10 + 20 = 32.
What is the greatest common factor of 20 30 and 50?
The greatest common factor (GCF) of 20, 30, and 50 is 10. To find the GCF, you need to determine the largest number that divides evenly into all three numbers. In this case, 10 is the largest number that is a factor of 20, 30, and 50. This can be calculated by finding the prime factors of each number and identifying the common factors among them.
How many factor pairs do 20 have and what are they?
3 pairs of factors. They are: 1 and 20 2 and 10 4 and 5 Pairs of factors are numbers that you multiply together to make that number, e.g. 4x5=20. Trust me I'm a teacher!
How do you find number of zeros in factorial 100?
The question, as asked, is difficult to answer, The number of zeros in factorial 100 is not the same as the number of 0s at the end of factorial 100 since there will be some before the end.The answer to the second question is easy:The number of zeros is determined by the number of 10s in the factors.Since 2s are common, this, in turn, depends on the number of 5s.In 100!, there are 20 multiples of 5 each of which will contribute a 5 to the factors of 100!.In addition there are 4 multiples of 52 = 25 each of which will contribute another 5 to the factors of 100!All in all, therefore, there are 24 5s giving 24 0s at the end of 100!
List all the common factors for 20 and 50?

What are the answers for math makes sense grade 6 page 46 and47?
List all the factors of each number. Which factors are prime factors between 20 and 28.
How do you find the greatest common factor of 16 20 and 28?
1). List all of the factors of 16. 2). List all of the factors of 20. 3). List all of the factors of 28. 4). Make a short list, comprised of any numbers that are on all three lists. These are the common factors of 16, 20, and 28. 5). Find the greatest number on the short list. That's the greatest common factor of 16, 20, and 28. If it is not 4, then an error has crept into your work, and you are doomed to return to Step-1 and eternally repeat the process until you get 4 .

How do you find the GCF of numbers using intersection of sets?
If you were to find the GCF of 20 and 36. Draw 2 overlapping circles. List "20" above one of the circles and "36" above the other. In the circle under "20", list the factors of 20 that are NOT factors of 36- 1, 5, 10, 20. In the other circle, list the factors of 36 that are NOT factors of 20- 1, 3, 6, 9, 12, 36. The factors that 20 and 36 that are in common are listed in the overlapping part of the circle or intersection- 2, 4. The greatest number in common is 4 (GCF). In other words, the largest number listed in the intersection is the GCF.
