NEVER!
A factor tree is strictly division. Factors at the end of a factor tree should all be whole numbers.
That doesn't really exist. A factor tree is a way to notate the process of finding the prime factorization of a given number. The greatest common factor, or GCF, is the largest number that can divide evenly with no remainder into a given set of numbers.
4 is a factor since 60 divided by 4 is 15, the others are not. To see if it is a factor, just see if it 60 divided by that number has a remainder or not. If the remainder is 0, it is a factor, if the remainder is non-zero it is not.
A factor = any number which can be divided into the given number with no remainder ie 1, 2, 61 and 122
IT IS PRIME there is no factor tree
Factor tree of 204
factor tree of 216
It is a factor.
No, 5 is not a factor of 42. A factor of a number divides it evenly with no remainder. When you divide 42 by 5, it does not divide evenly and leaves a remainder of 2. Therefore, 5 is not a factor of 42.
The definition of a factor is a number that divides evenly into another number with no remainder. Since no factor has a remainder, the GCF definitely can't have one.
The factor tree of 50:5025,25,5,25025,25,5,2
21
It is a factor of that number and leaves no remainder
