Answer:

GCF of 18 and 72 is 18

Step-by-step explanation:

<u>To find the GCF of two or more numbers</u>

we need two steps

Step 1: List the prime factors of each number.

Step 2: Multiply those factors all numbers have in common. If there are no common prime factors, the GCF is 1.

<u>To find the GCF of 18 and 72</u>

18 = 2 * 3* 3

72 = 2 * 2 * 2 * 3 * 3

Common prime factors 2, 3, 3

Therefore GCF = 2* 3 * 3 = 18

Lorico [155]

Answer:

Step-by-step explanation:

We have been given that dimensions of original photo are 4 inches by 6 inches. We want the photo on the poster to be of dimensions 3 feet by 4 1/2 feet.

First of all we will convert dimensions of poster from feet to inches.

$3\text{ feet}=3\times 12 \text{ inches}=36\text{ inches}$

$4\frac{1}{2}\text{ feet}=4.5\times 12 \text{ inches}=54\text{ inches}$

Now let us compare sides of our original photo with corresponding sides of poster.

$\frac{36}{4} =9$

Now let us compare the second pair of corresponding sides.

$\frac{54}{6} =9$

We have seen that sides of poster are 9 times the sides of our original photo, therefore, the scale factor of this dilation is 9.
