12=22x3
15=3x5
So the LCM of 2, 12 and 15 is 22x3x5 = 60
The least common factor of any set of positive integers is 1, and 1 does not have a prime factorization.
378
The Least Common Multiple of 75, 105 is 525.
All the even numbers and all the odd multiples of 5.
All even numbers are multiples of 2, so they have 2 in their prime factorization. No odd numbers are divisible by 2, so no add number has 2 in its prime factorization.
Prime factorization tells you what prime numbers multiply to get the number. You can see which numbers that number is divisible by to get the multiples and factors.
The least common factor of any set of positive integers is 1, and 1 does not have a prime factorization.
There is not a least common multiple of a single number, such as 130, because there cannot be a least common multiple without two or more numbers to compare. Common multiples are multiples that the numbers being compared have in common. The least common multiple is the smallest multiple that all the numbers being compared have in common.
you multiply them together

To find the GCF and the LCM you have to first at least try to use prime factorization. So use factor trees. Or for the LCM find th least common multiples of the number.
The LCM of 14 and 24 is 168.The prime factorization of 14 is 2 x 7;The prime factorization of 24 is 2 x 2 x 2 x 3,Their only common factor is 2 so LCM = 168168
Prime factorization helps to find the greatest common factor and the least common multiple which, in turn, help in the adding, subtracting and reducing of fractions.
