I think you mean the greatest common factor, the greatest common factor is 3.
The greatest common factor is the highest number that can be divided equally into two or more numbers.
If you mean 10, 82, and 16, the greatest common factor is 2. Otherwise, one number by itself cannot have a greatest common factor.
The greatest common factor of 3 and 57 is 3
If you mean 18, 42 and 36 then the GCF is 6
u mean "common" factor and 1 is the greatest
"Greatest common factor of an expression" is meaningless."Greatest common factor of two or more numbers" is the largest integerthat can divide evenly into each of the numbers.
like do you cross out the other numbers except the middle number
The numbers are relatively prime, or co-prime.
You probably mean greatest common factor. The greatest common factor, or GCF, is the largest integer that will divide evenly with no remainder into all the members of a given set of numbers.
The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.Since 840 is a single number, you could say that it shares all of its factors with itself. So the greatest factor of 840 is 840.You need at least two numbers to find a GCF.
