What are the common factor of 63 and 135?
1 Answer
HCF
All common factors
Explanation:
In this question I will show all the factors and the Highest Common Factor of 63 and 125, since you don't specify which one you want.
To find all factors of 63 and 135, we simplify them into their multiples. Take 63, for instance. It can be divided by 1 to equal 63, which are our first two factors,
Next we see that 63 can be divided by 3 to equal 21, which are our next two factors, leaving us with
Finally, we see that 63 can be divided by 7 to equal 9, our last two factors, which gets us
We then do the same with 135 to find its factor list is
The Highest Common Factor, or HCF, is the highest integer in two or more numbers which divides into these numbers to produce another integer. There are two ways to obtain the HCF. The first way is manually, by finding all the factors of 63
The second way is by dividing both numbers
Remembering always to divide numerator with numerator and denominator with denominator.
This process works with any two numbers which you want to find the HCF of, and can be simplified into this rule:
If
The HCF
I hope I helped!
