Final answer:
To rewrite 4x + 16 using a common factor, factor out 4 to get 4(x + 4). Option (B) is correct.
Step-by-step explanation:
To rewrite 4x + 16 using a common factor, we need to identify a number that can be factored out from both terms. In this case, the common factor is 4. We can rewrite 4x + 16 as 4(x + 4), which is option B.
A common factor is a whole number which is a factor of two or more numbers. The highest common factor (HCF) is the greatest factor that will divide into two or more numbers. The lowest common multiple (LCM) is the smallest multiple that is common to two or more numbers.
A common factor is a number that divides two or more numbers exactly. For instance, 10 and 20 have a common factor of 2 because they are both even. The greatest common factor (GCF) is the largest number that divides two or more numbers exactly. The numbers 10 and 20 have a greatest common factor of 10.
The greatest common factor (GCF) is the term used to describe the biggest number that can evenly divide a set of two or more numbers. It is also referred to as the greatest common divisor (GCD) or highest common factor (HCF).
