How to find the GCF between two terms

The video tutorial explains how to find the greatest common factor (GCF) of numbers and variables. It begins with an introduction to the concept of GCF, followed by a step-by-step guide on determining the GCF of two numbers by checking divisibility. The tutorial then moves on to finding the GCF of variables by comparing their exponents and degrees. The session concludes with clarifications and answers to questions about the process.

What is the first step in finding the GCF of two numbers?

• Multiply the two numbers

• Compare the numbers to find the largest common divisor

• Find the smallest number that divides both

• Add the two numbers together

Which method can be used to find the GCF of numbers?

• Start with the largest number and work downwards

• Start with the smallest number and work upwards

• Both methods can be used

• Neither method is effective

How do you determine the GCF of variables?

• By subtracting the exponents

• By finding the variable with the smallest degree

• By adding the exponents

• By multiplying the exponents

Why can't X^2 be the GCF if one term has X^1?

• Because X^2 cannot divide into X^1

• Because X^2 is larger than X^1

• Because X^2 is not a variable

• Because X^2 is not a number

What is the GCF of Z^2 and Z^2?

• Z^0

• Z^2

• Z^3

• Z^1
