If the numbers are prime numbers, the prime factor of each number is the number itself. If the numbers are not prime numbers, the prime factors of each number are each of the prime numbers by which the number in question can be divided without a remainder.
2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97
Prime factors are: 2,3,5,7,11,13,17,19.23,29,31,37,41,47,53,59,61,67,71,73,79,83,89,97
Factors of a number are numbers that can be multiplied together to get the number you are factoring.

How do you figure out prime factors?
All composite numbers can be expressed as unique products of prime numbers. This is accomplished by dividing the original number and its factors by prime numbers until all the factors are prime. A factor tree can help you visualize this.Example: 210210 Divide by two.105,2 Divide by three.35,3,2 Divide by five.7,5,3,2 Stop. All the factors are prime.2 x 3 x 5 x 7 = 210That's the prime factorization of 210.
How do you get answer 18 for sum of different prime factors of 550?
The distinct prime factors of 550 are 2, 5 and 11. They add up to 18.
What is the definition of the prime factorization?
The prime factors of a number by multiplying each other. You can also use exponents. a prime factorization is when you divide a number and see what all of the prime (odd) numbers make up that number. EX. 9 / \ 3 3 then you would circle the 3's because they are prime.
What number between 41 and 50 has a sum of 25 when all prime factors are added up?
29, 31, 37, 41, 43... making 5 in all
What is 3 factors of 100?
All the numbers up to 100 are factors in some numbers up to 100. For example, 1 is a factor of every number and 2 is a factor of all the even numbers. The numbers greater than 50 are only factors of themselves among the numbers up to 100, 95 is only a factor of itself, because the next number for which it is a factor is 190, which is greater than 100.
What are the composite number 100 up to 1?
All composite numbers have more than 2 factors but prime numbers have only 2 factors
Is 641 a prime number?
Yes 641 is a prime number. You would need to check all the factors up to the square root of 641. So you need to look at all the possible prime factors up to 25. Some can be skipped such as 2 and 3.
What strategy do you use to find factors?
Assuming you want all factors of a number: 1) Split a number into prime factors. 2) Combine the prime factors in all possible ways. To get the prime factors, you can systematically try out dividing the number by prime numbers, up to the number's square root (once the square of the prime number you try out is greater than the original number, you need not continue). For example, to find out prime factors of numbers up to 120, you only need to try dividing by 2, 3, 5, 7.
What goes into 9 and 100?
To find common factors, you first need to break the numbers up into their prime factors: 9=3x3 100=2x2x5x5 The next step would be to identify the common prime factors. In this case we can see that there are none, and thus the HCF, and indeed the only number that goes into both 9 and 100, is 1.
What are all off the even prime numbers up to 100?
' 2 ' is the only even prime number.
What number up to 100 has the most prime numbers?
64 and 96 have the longest prime factorizations in that range. If you're asking about distinct prime factors, quite a few are tied with three.
Is 41 a prime or composite number and why?
41 is a prime number because if you check all the factors: 2,3,4,5,6,7,8 etc. You will end up with the 2 factors: 1 and 41.
Is 2500 a square number?
To find out if a number is a square number, find its prime factors and check if all prime factors duplicate. In this example, the prime factors are: 2,2,5,5,5,5 We can see that all numbers are duplicates, and can be paired up. So 2500 is a square number of 2x5x5 or 50.
What are all the composite numbers between 30-40 that have prime factors that add up to 12?
The only number between 30 and 40 with distinct prime factors which add up to 12 is 35.
What all the prime nuers to 10?
Prime numbers up to 10: 2, 3, 5 and 7 Prime factors of 10: 2 and 5
Are prime factors and prime factorization the same?
No. Prime factors are the numbers that make up other numbers, but they have to be prime. Prime factorisation is the process of finding the prime numbers that create a number. This is when you multiply the prime numbers together and the product is the original number. For example: 20 5x4 5x2x2 This process is called prime factorisation. In this case, the prime numbers are 2, 2, and 5.
Does it matter what two factors you complete to a factor tree?
In doing the factor tree, you can start with any two factors of the given number. These factors maybe prime or composite. But the resulting factors in the factor tree should always be prime numbers. It means that you have to continue factoring unless you ended up with all prime factors.
