Free LCM Calculator determines the least common multiple (LCM) between 2 and 14 the smallest integer that is 14 that is divisible by both numbers.
Least Common Multiple (LCM) of 2 and 14 is 14.
LCM(2,14) = 14
Least common multiple or lowest common denominator (LCD) can be calculated in three ways;
Least common multiple can be found by multiplying the highest exponent prime factors of 2 and 14. First we will calculate the prime factors of 2 and 14.
Prime Factorization of 2

Prime factors of 2 are 2. Prime factorization of 2 in exponential form is:
2 = 21
Prime Factorization of 14
2 | 14 |
7 | 7 |

Prime factors of 14 are 2,7. Prime factorization of 14 in exponential form is:
14 = 21×71
Now multiplying the highest exponent prime factors to calculate the LCM of 2 and 14.
LCM(2,14) = 21×71
LCM(2,14) = 14
Factors of 2
List of positive integer factors of 2 that divides 2 without a remainder.
1, 2
Factors of 14
List of positive integer factors of 14 that divides 14 without a remainder.
1, 2, 7, 14
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 2 and 14, than apply into the LCM equation.
GCF(2,14) = 2
LCM(2,14) = ( 2 × 14) / 2
LCM(2,14) = 28 / 2
LCM(2,14) = 14
(i) The LCM of 14 and 2 is associative
LCM of 2 and 14 = LCM of 14 and 2

4. How to Find the LCM of 2 and 14?
Answer:
Least Common Multiple of 2 and 14 = 14
Step 1: Find the prime factorization of 2
2 = 2
Step 2: Find the prime factorization of 14
14 = 2 x 7
Step 3: Multiply each factor the greater number of times it occurs in steps i) or ii) above to find the lcm:
LCM = 14 = 2 x 7
Step 4: Therefore, the least common multiple of 2 and 14 is 14.
