Free LCM Calculator determines the least common multiple (LCM) between 2011 and 2015 the smallest integer that is 4052165 that is divisible by both numbers.
Least Common Multiple (LCM) of 2011 and 2015 is 4052165.
LCM(2011,2015) = 4052165
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 2011 and 2015. First we will calculate the prime factors of 2011 and 2015.
Prime Factorization of 2011
2011 | 2011 |
1 |
Prime factors of 2011 are 2011. Prime factorization of 2011 in exponential form is:
2011 = 20111
Prime Factorization of 2015
5 | 2015 |
13 | 403 |
31 | 31 |

Factors of 2015
List of positive integer factors of 2015 that divides 2015 without a remainder.
1, 5, 13, 31, 65, 155, 403, 2015
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 2011 and 2015, than apply into the LCM equation.
GCF(2011,2015) = 1
LCM(2011,2015) = ( 2011 × 2015) / 1
LCM(2011,2015) = 4052165 / 1
LCM(2011,2015) = 4052165
(i) The LCM of 2015 and 2011 is associative
