You can use prime factorization to find the GCF of a set of numbers. This often works better for large numbers, where generating lists of all factors can be time-consuming.
Here’s how to find the GCF of a set of numbers using prime factorization:
* List the prime factors of each number.
* Circle every common prime factor — that is, every prime factor that’s a factor of every number in the set.
* Multiply all the circled numbers.
The result is the GCF.
For example, suppose you want to find the GCF of 28, 42, and 70. Step 1 says to list the prime factors of each number. Step 2 says to circle every prime factor that’s common to all three numbers (as shown in the following figure).
As you can see, the numbers 2 and 7 are common factors of all three numbers. Multiply these circled numbers together:
2 · 7 = 14
Thus, the GCF of 28, 42, and 70 is 14.
Answer: 12

Answer:
3.64 × 10(raised to the power 7)
2.6 × 10⁴
Answer:
88 square inches
Step-by-step explanation:
if the entire square was shaded it would be 14 x 12 (as best as i can see)
the "cut out" or white part of the square is 8 x 10
Entire squre - cutout white part
14 x 12 - 8 x 10
168 - 80
88 sq in
Answer:
396.8
