Chapter 4.2, Problem 45E

To determine

To find greatest common factor of given monomial.

Answer to Problem 45E

  $s$

Explanation of Solution

Given Information: $r{s}^3,s^{3}t,r^{2}s{t}^2$

Formula used: Calculate Greatest common factor using factor method of monomial.

Calculation:

Greatest common factor of a variable is the biggest divisor that divides both the monomials.

Factors of $r{s}^3=r\times s\times s\times s$

Factors of $s^{3}t=s\times s\times s\times t$

Factors of $r^{2}s{t}^2=r\times r\times s\times t\times t$

Therefore, the GCF of variable is $s$

The final answer: $s$
