Common factors

Simple common factors

Example 1

In this example, the common factor is x
ax + bx = x(a + b)

Example 2

This time, the common factor is m
mx + my - mz = m(x + y - z)

Example 3

Here, 2a² is a common factor of each of the terms in the expression.
2a²x+4a³y²+8a⁴z³ = 2a² (x+2ay²+4a²z³)
