It helps to reduce fractions.
Same as the greatest common factor of 225 and 45 (where 45 is the remainder of the division of the two numbers).
You can't have the greatest common factor of just one number - for it to be common there needs to be at least 2 numbers.
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. So you do not need to use the division ladder or any other method!
The greatest factor that two or more numbers have in common is known as the greatest common factor, or GCF.
The greatest common multiple of any set of numbers is infinite. The greatest common multiple of any set of numbers will never be one.
The same as the greatest common factor of 70 and 26 - where 26 is the remainder of the division (196 divided by 70). Continue dividing, to get ever-smaller numbers - until one of the numbers is a multiple of the other. When this happens, the smaller of the numbers is the greatest common factor. This method is called the Euclid algorithm.
The greatest common factor of 99 and 25 is 1. There are not other numbers that are common between them.
The greatest common multiple of any two numbers is infinite.
No matter what you use, you still need at least two numbers to find a GCF.
There cannot be a greatest common factor if there are not at least two numbers to compare. The greatest common factor is the largest factor that all the numbers have in common - the largest factor that they all share.
There's no such thing as the greatest common factor of "a number". "Common" means "same for both". There can't possibly be anything 'common' until you have at least two separate numbers.
The greatest of the common factors of two or more numbers is the GCF
