what is a highest common factor in maths?

A common factor is a factor that is shared by two or more numbers. ... The highest common factor (HCF) is found by finding all common factors of two numbers and selecting the largest one. For example, 8 and 12 have common factors of 1, 2 and 4. The highest common factor is 4.

For two (integer) numbers, the greatest common factor, or gcf (also called the greatest common divisor , or gcd, and other names) is the largest integer that evenly divides both numbers.

We found the factors and prime factorization of 4 and 6. The biggest common factor number is the GCF number. So the greatest common factor 4 and 6 is 2.

The greatest common factor (GCF) of a set of numbers is the largest factor that all the numbers share.

The highest common factor (HCF) is found by finding all common factors of two numbers and selecting the largest one. For example, 8 and 12 have common factors of 1, 2 and 4. The highest common factor is 4.

It is therefore not the greatest common factor. In terms of numbers, the greatest common factor (gcf) is the largest natural number that exactly divides two or more given natural numbers. Example 1: 6 is the greatest common factor of 12 and 18.

When we find all the factors of two or more numbers, and some factors are the same ("common"), then the largest of those common factors is the Greatest Common Factor. Example: the GCF of 12 and 16 is 4, because 1, 2 and 4 are common factors of both 12 and 16, and 4 is the greatest of them.

The factors of 12 are : 1, 2, 3, 4, 6, 12. The factors of 15 are : 1, 3, 5, 15. 1 and 3 are the only common factors (numbers which are factors of both 12 and 15). Therefore, the highest common factor of 12 and 15 is 3.

The greatest common factor (GCF) is the greatest factor that is common to two or more numbers (they share it). The greatest common factor of two (or more) numbers is the product of all the prime factors the numbers have in common.
848434
The greatest number that is a factor of two (or more) other numbers. When we find all the factors of two or more numbers, and some factors are the same ("common"), then the largest of those common factors is the Greatest Common Factor.

Highest common factor HCF of two consecutive odd numbers is always one 1. Between their factors 1 is common so their highest common factor HCF is 1.

We found the factors and prime factorization of 4 and 8. The biggest common factor number is the GCF number. So the greatest common factor 4 and 8 is 4.

Try Factor a Polynomial by Finding Its Greatest Common Factor. For a number, The Greatest Common Factor (GCF) is the largest number that will divided evenly into that number. For example, for 24, the GCF is 12. For a polynomial, the GCF is the largest polynomial that will divide evenly into that polynomial.

Factors of a number are any numbers which divide into a given number evenly. Common factors are 1, 2, 3, 4, 6, & 12. The largest of these (12) is the greatest common factor (GCF). Listing factors is one way to find the GCF.

We found the factors and prime factorization of 5 and 10. The biggest common factor number is the GCF number. So the greatest common factor 5 and 10 is 5.

A common factor is a number that can be divided into two different numbers, without leaving a remainder. Often numbers can share more than one common factor. It is possible to find the common factors of more than two numbers.

The prime factors they have in common are 3 x 5. 3 x 5 = 15. The greatest common factor is 15. When two numbers have no prime factors in common, their greatest common factor is 1.
