What is the greatest co on factor of 9 15 and 21?

Oh, dude, the greatest common factor of 9, 15, and 21 is 3. It's like the superhero that swoops in to save the day, dividing all those numbers without breaking a sweat. So yeah, 3 is the chosen one in this math problem.


What is the greatest common factor of 133 and 228?

To find the greatest common factor (GCF) of 133 and 228, we first need to find the factors of each number. The factors of 133 are 1, 7, 19, and 133. The factors of 228 are 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, and 228. The common factor between the two numbers is 19, making it the greatest common factor of 133 and 228.


Is the greatest common factor of two even numbers always even?

Assuming the second even number is equal to 4 or greater, than the highest common factor of the two numbers is equal to an even number 2 or greater. Why can't an odd factor be used? Any odd factor must be multiplied by (at least) 2 to create an even product (ie. the 1st even number). That same odd factor must be multiplied by (at least 2) and any other number to create a 2nd even product, thereby making the Greatest Common Factor (at least) 2 times the odd number....which is an even number.


What goes into 26 and 45?

The numbers that go into both 26 and 45 are their common divisors. The divisors of 26 are 1, 2, 13, and 26, while the divisors of 45 are 1, 3, 5, 9, 15, and 45. The only number that goes into both 26 and 45 is 1, making it their greatest common divisor (GCD). Thus, 1 is the only common factor of the two numbers.


What is the GCF of 4 8 and 24?

Listen up, honey. The Greatest Common Factor (GCF) of 4, 8, and 24 is 4. Why? Because 4 is the largest number that divides evenly into all three of those numbers. So, there you have it, simple as that.
