How do you know when you have found the longest factor string for a number?
All of the factors are prime.
What are factor lists?
Not to overstate the obvious, but factor lists are lists of factors. Once you have found all the factors of a number, it is customary to list them from least to greatest.
What is the least number that has four odd factors that are all the same each factor is greater than 1 and can only have 1 and itself as factors explain how you found the number?
The smallest odd prime number greater than one is 3. 3 x 3 x 3 x 3 = 81
How do you know when you've found all the factors for a number?
If you know the prime factorization of a number, you can find out the total number of factors.Example: 21021 x 31 x 51 x 71 = 210Add one to the exponents and multiply them.2 x 2 x 2 x 2 = 16, the total number of factors.You know that 1, 2, 3, 5, and 7 are factors. You need three more to get halfway.2 x 3 = 62 x 5 = 102 x 7 = 14Divide all those numbers into 210.1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210You know you've found all the factors of a number when the next first factor exceeds its corresponding second factor. For example, after you found that 4 was a factor of 24 and 5 was not, you would see that 6, the next factor of 24, had already been included in a pair of factors. Thus, all the factors have been found.
How divisibility rules can help you find common factors?
Divisibility rules help you find the factors of a number. Once you've found the factors for two or more numbers, you can find what they have in common. Take 231 and 321. If you know the divisibility rules, you know that they are both divisible by 3, so 3 is a common factor.
How do you know when you found the longest possible string of factors for a number?
When each one of them is a prime.
How do you know when you have found the longest string of factors for a number?
When all the factors are prime.
How do you know when you have found the longest factor string for a number?
All of the factors are prime.
How do you know when you have found the longest possible factor string of a number?
When all of the numbers are prime.
How do you know when you've found all the factors of a number?
If you multiply all the prime factors you've found together and the result is the number, you have found all of them.
What is the longest factor string you found?
The longest factor string of any composite number is its prime factorization.
How do you know you found all factors to a number?
How to know that you found all the factors for example my teacher taught me that when u reach a double diget number that is all the factors. ( 6x6)-~ double diget number
What is the difference between finding the factors of a number and finding the prime factors of a number?
No difference. Once you've found the factors of a number, the prime numbers on that list are the prime factors.
How do you know if a number is abundant or deficiant?
First to be able to find an abundant number you have find all the factors of any number. Then add them all up. If the total is bigger than the number you found out the factors of then it is an abundant number and if the total is less than the number you found out the factors for it is a deficiant number and finally if the total is the same number as the one you found out the factors for it is called a perfect number. Thanks for learning from me. I hope you have understood what i have typed. Bye!
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.
Does everyone go to jail who is found guilty of child abuse?
No. It depends on a number of factors and the punishment is unique to each case. It is possible for the courts to assign the convicted person to parole or probation. It is possible the person may only pay a fine.
When looking for a factors of a composite number how do you know you have found the right answer?
List them all, and multiply to see if you get the original number.
