What is the highest common factor 35 and 45?
7 * 5 = 359 * 5 = 45The highest common factor is 5.
What is the lowest common multiple for 5 and 6?
The lowest common multiple of 5 and 6 is 30.
What is the greatest common factor of 15 and 100?
One 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 100 are 1, 2, 4, 5, 10, 20, 25, 50, and 100.The common factors are 1 and 5. Therefore, the greatest common factor is 5.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 100 are 2, 2, 5, and 5.The prime factors in common are 5, so the greatest common factor is 5.ANSWER: 5The GCF is 5.
What is the least common multiple for 5 and 20?
5
What is the least common multiple of 5 and 23?
The least common multiple of two numbers is the product of the two numbers divided by their greatest common factor. The greatest common factor of 5 and 23 is 1. (See related question "What is the greatest common factor of 5 and 23?" for this calculation.) So, the least common multiple is 5 x 23 ÷ 1 = 115.
