Least Common Multiple of 11 and 14

Least common multiple or lowest common denominator (LCD) can be calculated in three ways;

• Least Common Multiple of 11 and 14 by Prime method
• Least Common Multiple of 11 and 14 with GCF Formula

Least common multiple can be found by multiplying the highest exponent prime factors of 11 and 14. First we will calculate the prime factors of 11 and 14.

Prime Factorization of 11

Prime factors of 11 are 11. Prime factorization of 11 in exponential form is:

11 = 11¹

Prime Factorization of 14

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 11 and 14.

LCM(11,14) = 2¹×7¹×11¹
LCM(11,14) = 154

Factors of 11

List of positive integer factors of 11 that divides 11 without a remainder.

1, 11

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 11 and 14, than apply into the LCM equation.

GCF(11,14) = 1
LCM(11,14) = ( 11 × 14) / 1
LCM(11,14) = 154 / 1
LCM(11,14) = 154

(i) The LCM of 14 and 11 is associative

LCM of 11 and 14 = LCM of 14 and 11
