## What is factor formula?

What Is a Factors Formula? The factors formula for a number gives the total number of factors of a number. For a number N, whose prime factorization is Xa × Yb × Zc, (a+1) (b+1) (c+1) is the total number of factors.

### What is factor in algorithm?

Factors of a Number are the whole numbers which on multiplication of them form that number. For Eg. Factor of 12 are 2,4,6,3. 2 X 6 = 12 and 4 X 3 = 12 and their vice versa. Factors are the essential element in mathematics.

**What is factor and example?**

factor, in mathematics, a number or algebraic expression that divides another number or expression evenly—i.e., with no remainder. For example, 3 and 6 are factors of 12 because 12 ÷ 3 = 4 exactly and 12 ÷ 6 = 2 exactly. The other factors of 12 are 1, 2, 4, and 12.

**What is b2 4ac?**

For the quadratic equation ax2 + bx + c = 0, the expression b2 – 4ac is called the discriminant. The value of the discriminant shows how many roots f(x) has: – If b2 – 4ac > 0 then the quadratic function has two distinct real roots. – If b2 – 4ac = 0 then the quadratic function has one repeated real root.

## What is ML factor?

Factor analysis is one of the unsupervised machine learning algorithms which is used for dimensionality reduction. This algorithm creates factors from the observed variables to represent the common variance i.e. variance due to correlation among the observed variables.

### What is a factor of 6?

The factors of 6 are the numbers that divide 6 exactly without leaving the remainder. In other words, the factors of 6 are the numbers that are multiplied in pairs resulting in an original number 6. As 6 is an even composite number, it has many factors other than 1 and 6. Thus, the factors of 6 are 1, 2, 3 and 6.

**What is a factor of 8?**

A number or an integer that divides 8 exactly without leaving a remainder, then the number is a factor of 8. As the number 8 is an even composite number, it has more than two factors. Thus, the factors of 8 are 1, 2, 4 and 8.

**What is the factor of20?**

The factors of 20 are 1, 2, 4, 5, 10 and 20.

## What is the value of B² 4ac?

It shows the nature of the roots of any quadratic equations where a, b, and c are real numbers. Comparing the equation with the standard form. Therefore, the value of b2 – 4ac is 9.

### What are the factoring rules?

Algebra II/Factoring Rules

- 1 1. GCF.
- 2 2. Difference of two squares: a2 – b2 = (a+b)(a-b)
- 3 3. Trinomial whose leading coefficient is one.
- 4 4. Sum of two cubes: a3 + b3 = (a+b)(a2 – ab + b2)
- 5 5. Perfect Square Trinomials: a2 + 2ab + b2 = (a+b)2
- 6 6. Factor by Grouping.

**What is the fastest factoring algorithm?**

The Quadratic sieve algorithm is the fastest known classical algorithm for factoring numbers under 10100.

**What is the difference between factor analysis and PCA?**

The mathematics of factor analysis and principal component analysis (PCA) are different. Factor analysis explicitly assumes the existence of latent factors underlying the observed data. PCA instead seeks to identify variables that are composites of the observed variables.
