Least Common Multiple of 33 and 37

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

• Least Common Multiple of 33 and 37 by Prime method
• Least Common Multiple of 33 and 37 with GCF Formula

Least common multiple can be found by multiplying the highest exponent prime factors of 33 and 37. First we will calculate the prime factors of 33 and 37.

Prime Factorization of 33

Prime factors of 33 are 3,11. Prime factorization of 33 in exponential form is:

33 = 3¹×11¹

Prime Factorization of 37

Prime factors of 37 are 37. Prime factorization of 37 in exponential form is:

37 = 37¹

Now multiplying the highest exponent prime factors to calculate the LCM of 33 and 37.

LCM(33,37) = 3¹×11¹×37¹
LCM(33,37) = 1221

Factors of 33

List of positive integer factors of 33 that divides 33 without a remainder.

1, 3, 11, 33

Factors of 37

List of positive integer factors of 37 that divides 37 without a remainder.

1, 37

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 33 and 37, than apply into the LCM equation.

GCF(33,37) = 1
LCM(33,37) = ( 33 × 37) / 1
LCM(33,37) = 1221 / 1
LCM(33,37) = 1221

(i) The LCM of 37 and 33 is associative
