How do you find the HCF of 4 numbers?
HCF of 4 and 10 is the divisor that we get when the remainder becomes 0 after doing long division repeatedly.
- Step 1: Divide 10 (larger number) by 4 (smaller number).
- Step 2: Since the remainder ≠ 0, we will divide the divisor of step 1 (4) by the remainder (2).
- Step 3: Repeat this process until the remainder = 0.

What are the four types of factoring?
The four main types of factoring are the Greatest common factor (GCF), the Grouping method, the difference in two squares, and the sum or difference in cubes.
How many ways can you find HCF?
We can find HCF and LCM of given natural numbers by two methods i.e., by prime factorization method or division method. In the prime factorization method, given numbers are written as the product of prime factors.

Why does the factoring calculator only show positive factors?
For positive integers the calculator will only present the positive factors because that is the normally accepted answer. For example, you get 2 and 3 as a factor pair of 6. If you also need negative factors you will need to duplicate the answer yourself and repeat all of the factors as negatives such as -2 and -3 as another factor pair of 6.
