The greatest common factor of 6, 8, and 12 is 2.

The greatest common factor of 10, 15, and 20 is 5.

The greatest common factor of 20 and 45 is 5.

The greatest common factor of 42 and 65 is 14.

histogram
histogramme m

homogeneous
homogeneous

Homogeneous. A homogeneous polynomial is a polynomial in which all its terms are of the same degree.

It is a homogeneous polynomial of degree 3, while: is a homogeneous polynomial of degree 2.

Note: The degree of the term is obtained by adding the base (power) of X and 7, thus x3y4 is of degree 7. Similarly, a homogeneous equation can be defined. For example:

x3+x2y+3xy2+7y³=0

It is a homogeneous equation of degree 3.
