Being able to factor numbers is a key skill, one that's necessary to learn and perform many other math skills down the line, like working with fractions. there's more than one correct way to do it. The technique listed below isn't always the fastest way, but it's the easiest to describe and follow.
. Remember, a factor is a number which divides INTO another number without leaving a remainder. For example, 6 is a factor of 12, but 6 is not a factor of 13. A prime factor is a number such as 2, 3, 5, 7, 11, 13, or 17 (to name a few) --- a number that can only be divided by itself and 1. (Please be careful: just because a number is odd, doesn't mean it's prime! 9 and 15 are just two examples of non-prime odd numbers.)
Our process will be: find the smallest prime factor of our number, divide our number by that prime, then repeat the process with the quotient until we reach 1.
The factor numbers are 3 and -17.
One of the numbers is a factor of the other.
The HCF is always a factor of the LCM of two numbers. The HCF is a factor of both the numbers which are factors of their LCM. Thus the HCF is also a factor of the LCM of the two numbers.
The largest common factor of two or more numbers is the factor that goes into both numbers. Such as: the largest common factor of 2 and 4 is 2 The largest common factor of two or more numbers is the factor that goes into both numbers. Such as: the largest common factor of 2 and 4 is 2 That's the greatest common factor, or GCF.
Yes. Factors are just numbers. All numbers have factors.
One is a factor of all nonzero numbers.
A number that is a factor of two or more numbers is simply a common factor
All numbers with 12 as a factor have 2 as a factor, but not all have 10 as a factor.
Yes, if one of the numbers is a factor of the other.
All numbers have factors. Some factors are prime numbers, some are composite numbers. A factor that is a composite number is a composite factor.
Numbers that contain 24 as a factor are known as the multiples of 24.
Prime numbers have one factor pair.
