What is the greatest common factor of 15 and 75?

Since 15 is a factor of 75, and 15 is its own largest factor, the greatest common factor must be 15.Another way to determine the greatest common factor is to find all the factors of the numbers and compare them.The factors of 15 are 1, 3, 5, and 15.The factors of 75 are 1, 3, 5, 15, 25, and 75.The common factors are 1, 3, 5, and 15. Therefore, the greatest common factor is 15.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 15 are 3 and 5.The prime factors of 75 are 3, 5, and 5.The prime factors in common are 3 and 5, so the greatest common factor is 3 x 5 = 15.It is 15


What is the least common factor of 9 and 15?

Most of the time, math questions are about the greatest common factor or the least common multiple, not the least common factor. The least common factor of any two numbers would typically be 1. The factors of 15 are 1, 3, 5, and 15. The factors of 9 are 1, 3, and 9. The greatest common factor is 3. The prime factors of 15 are 3 and 5. The prime factors of 9 are 3 and 3. So, take the 3 and 5 prime factors of 15, and then the second 3 prime factor of 9, multiply them together, so 3 x 5 x 3 = 45 is the least common multiple.
