Least Common Multiple of 11 and 34

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

• Least Common Multiple of 11 and 34 by Prime method
• Least Common Multiple of 11 and 34 with GCF Formula

Least common multiple can be found by multiplying the highest exponent prime factors of 11 and 34. First we will calculate the prime factors of 11 and 34.

Prime Factorization of 11

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

11 = 11¹

Prime Factorization of 34

Prime factors of 34 are 2,17. Prime factorization of 34 in exponential form is:

34 = 2¹×17¹

Now multiplying the highest exponent prime factors to calculate the LCM of 11 and 34.

LCM(11,34) = 2¹×11¹×17¹
LCM(11,34) = 374

Factors of 11

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

1, 11

Factors of 34

List of positive integer factors of 34 that divides 34 without a remainder.

1, 2, 17, 34

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 11 and 34, than apply into the LCM equation.

GCF(11,34) = 1
LCM(11,34) = ( 11 × 34) / 1
LCM(11,34) = 374 / 1
LCM(11,34) = 374

(i) The LCM of 34 and 11 is associative

LCM of 11 and 34 = LCM of 34 and 11
