Answer 1

please mark me as brainliest
Answer:

45

Explanation:

Let's do a prime factorization of the two numbers:

180=2×90=2×2×45=2×2×3×3×5
225=5×45=000000000000000000003×3×5×5

And now let's find what's in the GCF by seeing what is common to both:

2

There are 2s in 180 but not 225, so there are no 2's in the GCF.

3

There are two 3s in both 180 and 225, and so the GCF has two 3s.

5

There is one 5 in 180 and two in 225, and so the GCF has one 5.

And now let's put it all together:

3×3×5=9×5=45

45×4=180
45×5=225

Answer 2

Here your answer is
The answer is. 45
