What is the gcf of 20,45,and 75?

Question

please tell me

Answer 1

The greatest common factor is 5, because it's the highest factor that you can divide each of these numbers by.  Here's the list of factors for each number, and you can see that 5 is the highest number that is on all three lists, making it the gcf.

Factors of 20: 1,2,4,5,10,20

Factors of 45: 1,3,5,9,15,45

Factors of 75: 1,3,5,15,25,75

Answer 2

GCF of 20= 10

GCF of 45= 15

GCF of 75= 25

Answer 3

The answer is 5

Answer 4

its 5!

1st. list down all the factors:

20: 1,2,4,5,10,20

45: 1,5,9,45

75: 1,3,5,15,25,75

Then, find the greatest common factor, which is 5!

Hope this helps!

Answer 5

What is the GCF of 20, 45, and 75?

GCF is an acronym for 'Greatest Common Factor'. The Greatest Common Factor (GCF) is the greatest (or highest) number that is a factor (or divisible) by the given set of numbers (in this case, 20, 45, and 75).

Here are the factors for each number:

20: 1, 2, 4, 5, 10, 20

45: 1, 3, 5, 9, 15, 45

75: 1, 3, 5, 15, 25, 75

5 is the GCF for the given set of numbers as they are all divisible by 5. 15 wouldn't work because only 45 and 75 are divisible by 15. Neither would 10 for the same reason.

Now, factors of 200, 250, and 400 are:

200: 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, 200

250: 1, 2, 5, 10, 25, 50, 125, 250

400: 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400

So, the GCF for this set of numbers is 50.
