Factoring can be simple. In order to find the factors of a number, a person finds all the numbers that divide into the number evenly.
Sure, just tell me what the numbers are.
There are two ways in which the factors can be given. You are given all the prime factors (and their multiplicity). In that case simply multiply them all together. Or You are given each factor. In this case, the biggest of these is the number.
360, 420 and 480 all have 24 factors.
-- List all factors of the first number. -- List all factors of the second number. -- If there are more than two numbers, list all factors of each one. -- Find the set of factors that are on every list. -- Find the greatest factor in the set.
You can quickly find the factors for even numbers 50 to 100 by dividing each number by all possible factors (starting from 2) until reaching the square root of the number. If a number is divisible without a remainder, then it is a factor of that even number. Repeat this process for each even number between 50 and 100.
No because, all you have to know is your multiplication to help you.
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.
The question is garbled but I suspect that the answer is "a prime number".
No. There are techniques to find if it is prime
List all the factors of each number. Which factors are prime factors between 20 and 28.
