Find the greatest common factor of the terms in the expression $3a^2b^2+4b^2c^2+12a^2b^2c^2$.


The given expression is $3a^2b^2+4b^2c^2+12a^2b^2c^2$.

To do:

We have to find the greatest common factor of the terms in the given expression.



A common factor of two or more numbers is a factor that is shared by the numbers. The greatest common factor (GCF) of those numbers is found by finding all common factors of the numbers and selecting the largest one.

The terms in the given expression are $3a^2b^2, 4b^2c^2$ and $12a^2b^2c^2$.

The numerical coefficient of $3a^2b^2$ is $3$

The numerical coefficient of $4b^2c^2$ is $4$

The numerical coefficient of $12a^2b^2c^2$ is $12$

This implies,




GCF of $3, 4$ and $12$ is $1$

The common variable in the given terms is $b$

The power of $b$ in $3a^2b^2$ is $2$

The power of $b$ in $4b^2c^2$ is $2$

The power of $b$ in $12a^2b^2c^2$ is $2$

The monomial of common literals with the smallest power is $b^2$


The greatest common factor of the three terms in the given expression is $b^2$.
