Since a factor is a number that can be multiplied by a whole number and give you your "given number" then a good strategy is to first write down 1 and the number itself. Then, if the number is even, write down 2. Once you have done that, it is a case of dividing by numbers up to half of the given number, after this point no number can be a factor.

E.G.

Factors of 64:

1, 2, 4, 8, 16, 32, 64

Notice how after 32 only 64 can be a factor of 64 since any numbers between cannot be multiplied by a whole number to get 64.

Hope this helped!

How do you find two pairs of numbers with the given number as their least common multiple?

This will be difficult to answer accurately as you haven't given us the given number but as a general rule, list the given number with two of its factors. If the given number was 15, (15, 5) and (15, 3) both have an LCM of 15.


To find weather the given no is prime or not?

Prime numbers have two and only two factors. If the number has more than two factors, it is not prime.


How is prime factorization different from finding factors of a number?

All numbers have factors. Some factors are prime numbers, some are composite numbers, one is neither. When finding the factors of a number, you find all the factors. The prime factorization is a multiplication string of just prime factors that will total the given number.


Why is 836475 not a prime number?

A number which is divisible by itself and 1 is called prime number. A prime number has only two factors.But, 836475 is also divisible by5, i.e. 836475 has more than two factors.Therefore, the given number is not prime.In order to show that given number is not prime there is no need to find all the factors, we should show that given number has more than two factors.


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.


How do you find factors of a number?

You could find factors of a number with the guess and check method. You could also type your number into a factor calculator and get your factors that way.


What are factors greatest common factor?

Given two numbers, you find the largest possible number, which is a factor of both numbers. One way to do this is to find the prime factors of each number, then collect the prime factors that are common to both numbers, then multiply these together to get the GCF. If there are not common prime factors, then 1 is the GCF, since 1 is a factor of every whole number.


What number has the most factors?

There is no such number. You can always find a number that has yet more factors.


How do you find the common primes of a number?

Technically, you can't. You can find the prime factors of a number. If you compare those prime factors to the prime factors of another number, you will see if they have any prime factors in common.

Would you rather find the factors of a number or the prime factors?

I would rather find the prime factors.


Would you rather find all the factors of a number or find all the prime factors of a number?

Once all the prime factors of a number have been found, the number of factors the number has and what they are can be found. I'd be finding the prime factors first before finding all the factors of a number, so I'd rather find all the prime factors as it means I can stop before I have to do more work in finding all the factors.


How do you find all of the factors of a number?

You find what half of the number is and then you look through all of the numbers and whichever numbers go into that number evenly are factors.
