What is the GCF of 49 and 63?

The greatest common factor (GCF) of 49 and 63 is: 7

To find the GCF, you simply gather up the factors for both of the numbers, but make sure you only write out the factors that are less or equal to 49, since you shouldn't go over the minimum number.

Factors of 49: 1, 7, 49
Factors of 63: 1, 3, 7, 9, 21

Now that we know the factors of both of the numbers, we should find the most common between them. Which numbers are common between the two numbers? The common factors of them are 1 and 7, but we are looking for the greatest common factor. Now, which is the greatest of 1 and 7? It is 7, since 7 is a higher number than 1.

Hi! mark me brainliest if i : )y = 0.213x – 352.0    represents this linear model shown in the data table.plug in the values of x into the equation for a double check.let's try 1980.y = 0.213(1980) – 352.0y = 69.74which is closest to the 70.1 whereas other options do not satisfy the condition.
