No, that's just a factor. A common factor is when that factor is also a factor of another number.
No
It is 1 because it is the highest number that will divide evenly into both numbers leaving no remainders
Greatest Common Factor is GCF
Because they both will divide into 1000 evenly with no remainders
2 is a factor of 144. For it to be common, it needs to be compared to another set of factors.
The Greatest Common Factor (GCF) of 40 and 2 is 2.
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.
Factor, in maths terms means "a number that divides into a given number with no remainders". You may be asked to find the "highest common factor" that two number share - this is the "biggest number that divides into both the given numbers, with no remainders".
1 is a factor of 6. factors are those numbers which divide into other numbers without remainders multiples are those numbers which are other numbers multiplied by another number. 1 is a factor of 6 → 6 is a multiple of 1.
The idea here is to factor each of the numbers. Then look for common factors, i.e., factors that appear in both numbers.
It is 1 because it is the highest number that will divide evenly into both numbers leaving no remainders
The GCF is 15 because it is the highest number that will divide exactly into 135 and 120 leaving no remainders.
It is 28 because it is the highest number that will go into both numbers evenly and leaving no remainders
It is 12 because 12 is the highest common factor of both number that will divide into them evenly and leaving no remainders.
The greatest common factor between 504 and 336 is 168. You would find this by listing all the factors of 504 and 336 and choosing the highest one that would divide them evenly with no remainders.
Another name for the least common factor is 1.
To find a common factor, you need another number to have common (shared) factor with. However, with any set of numbers, the Least Common FACTOR (the smallest (positive) whole number which divides into each of the numbers without any remainder) will always be 1.
