The factor tree finds the prime factorizations The prime factorizations find the GCF and LCM.
Example 30 and 42:
30
15,2
5,3,2
42
21,2
7,3,2
2 x 3 x 5 = 30
2 x 3 x 7 = 42
Select the common factors.
2 x 3 = 6, the GCF
Combine the factors, eliminating duplicates.
2 x 3 x 5 x 7 = 210, the LCM
Check it.
30 x 42 = 1260
210 x 6 = 1260
It checks.

Find HCF of 260 and 560?
HCF is the highest common factor of two or more numbers. HCf of 260 and 560 is 20.
What is the HCF of 1296 and 960?
The Highest Common Factor (HCF) of 1296 and 960 is the largest positive integer that divides both numbers without leaving a remainder. To find the HCF, we can use the Euclidean algorithm, which involves dividing the larger number by the smaller number and then using the remainder as the new divisor in the next iteration. By repeating this process, we find that the HCF of 1296 and 960 is 48.
What is the highest common factor of 210 and 147?
The highest common factor (HCF) of 210 and 147 is the largest positive integer that divides both numbers without leaving a remainder. To find the HCF, you can use the Euclidean algorithm, which involves dividing the larger number by the smaller number and then using the remainder as the new divisor in the next iteration. Continuing this process, you find that the HCF of 210 and 147 is 21.
What is the HCF of 336 and 384?
The Highest Common Factor (HCF) of 336 and 384 is the largest number that divides both 336 and 384 without leaving a remainder. To find the HCF, you can use the Euclidean algorithm, which involves dividing the larger number by the smaller number, then using the remainder as the divisor in the next iteration. Continuing this process will eventually lead to a remainder of 0, at which point the divisor will be the HCF. In this case, the HCF of 336 and 384 is 48.
Can you find the HCF of 3 numbers using euclids division lemma?
Yes.First find the HCF of two of the numbers, then find the HCF of that answer and the third number.In this way you could find the HCF of as many numbers as you want.
Why do you factor numbers in algebra?
to find a factor of a number you have to 1. find the hcf (highest common factor) 2. find how many times the hcf goes into your number AND THAT IS YOUR ANSWER!
If b is a factor of a find HCF of a and b?
b
What is Highest common factor (HCF) of 27?
Two or more numbers are needed to find their HCF
Find HCF of 260 and 560?
HCF is the highest common factor of two or more numbers. HCf of 260 and 560 is 20.
Can the HCF of two numbers be a factor of their LCM?
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.
What is the highest common factor of 130 and 165?
The highest common factor (HCF) of two numbers is the largest positive integer that divides both numbers without leaving a remainder. To find the HCF of 130 and 165, you can use the Euclidean algorithm, which involves dividing the larger number by the smaller number and then using the remainder as the new divisor. By repeating this process, you will find that the HCF of 130 and 165 is 5.
How do you find the quotient in simplest form?

What is the HCF of 4 6 and 8?
Ah, finding the Highest Common Factor, or HCF, is like finding a happy little tree in a forest. The HCF of 4, 6, and 8 is 2, like a sturdy trunk supporting the branches of a tree. Just like how each tree is unique, each set of numbers has its own special HCF waiting to be discovered.
