Least Common Multiple of 37 and 43

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

• Least Common Multiple of 37 and 43 by Prime method
• Least Common Multiple of 37 and 43 with GCF Formula

Least common multiple can be found by multiplying the highest exponent prime factors of 37 and 43. First we will calculate the prime factors of 37 and 43.

Prime Factorization of 37

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

37 = 37¹

Prime Factorization of 43

Prime factors of 43 are 43. Prime factorization of 43 in exponential form is:

43 = 43¹

Now multiplying the highest exponent prime factors to calculate the LCM of 37 and 43.

LCM(37,43) = 37¹×43¹
LCM(37,43) = 1591

Factors of 37

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

1, 37

Factors of 43

List of positive integer factors of 43 that divides 43 without a remainder.

1, 43

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 37 and 43, than apply into the LCM equation.

GCF(37,43) = 1
LCM(37,43) = ( 37 × 43) / 1
LCM(37,43) = 1591 / 1
LCM(37,43) = 1591

(i) The LCM of 43 and 37 is associative

LCM of 37 and 43 = LCM of 43 and 37
