Least Common Multiple of 39 and 41

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

• Least Common Multiple of 39 and 41 by Prime method
• Least Common Multiple of 39 and 41 with GCF Formula

Least common multiple can be found by multiplying the highest exponent prime factors of 39 and 41. First we will calculate the prime factors of 39 and 41.

Prime Factorization of 39

Prime factors of 39 are 3,13. Prime factorization of 39 in exponential form is:

39 = 3¹×13¹

Prime Factorization of 41

Prime factors of 41 are 41. Prime factorization of 41 in exponential form is:

41 = 41¹

Now multiplying the highest exponent prime factors to calculate the LCM of 39 and 41.

LCM(39,41) = 3¹×13¹×41¹
LCM(39,41) = 1599

Factors of 39

List of positive integer factors of 39 that divides 39 without a remainder.

1, 3, 13, 39

Factors of 41

List of positive integer factors of 41 that divides 41 without a remainder.

1, 41

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 39 and 41, than apply into the LCM equation.

GCF(39,41) = 1
LCM(39,41) = ( 39 × 41) / 1
LCM(39,41) = 1599 / 1
LCM(39,41) = 1599

(i) The LCM of 41 and 39 is associative

LCM of 39 and 41 = LCM of 41 and 39
