There is no Greatest Common Factor (GCF) for a single number. The Greatest Common Factor (GCF) is the largest factor common to two or more given numbers.
A common factor of two numbers is a factor of both numbers. The largest factor that a number has is itself, so the greatest factor that the smaller number can have is itself. If it is a factor of the larger number then it would be the greatest common factor. If not , the greatest common factor would have to be smaller.
The greatest factor of any positive number is the number itself. The greatest common factor of 15 and 25 is 5.
Lots of numbers are NOT common factors. For example, 5, 7, 100...Get the greatest common factor of both numbers. All common factors are factors of this greatest common factor. Note that all of them must needs be less than or equal to the greatest common factor. Any other number is NOT a common factor.
The greatest common factor (GCF) refers to a factor that is COMMON to two or more numbers. You have only one number in the question! The greatest factor of any number is itself.
The GCF of the numbers is the greatest common factor no matter what their relationship is. When one number is a multiple of another number, the GCF is the smaller number.
The greatest common FACTOR of 90 and 108 is 18. The LEAST common multiple is 540. There can be no greatest common multiple since double that number will be a greater common multiple.
When one number is a multiple of the other, the greatest common factor of the two is the smaller number.
71 is a prime number, so its only factors are 1 and 71. Unless n is a multiple of 71, the greatest common factor is 1. If n is a multiple of 71, the greatest common factor is 71.
10 and 120
The greatest common multiple is an infinite number and not very practical for everyday use. The greatest common factor of those two numbers is 11.
The other number.
The greatest common factor, or GCF, is the largest number that can go into a set of given numbers evenly. The least common multiple, or LCM, is the smallest number that a given set of numbers can go into evenly.
There is no answer. There cannot be a lowest common multiple of a single number, such as 30, because "common multiple" means a multiple that two or more numbers have in common. Likewise, there cannot be a highest common factor of a single number, such as 3, because "common factor" means a factor that two or more numbers have in common.
Only if you're comparing a number to itself.
