Least Common Multiple of 31 and 37

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

• Least Common Multiple of 31 and 37 by Prime method
• Least Common Multiple of 31 and 37 with GCF Formula

Least common multiple can be found by multiplying the highest exponent prime factors of 31 and 37. First we will calculate the prime factors of 31 and 37.

Prime Factorization of 31

Prime factors of 31 are 31. Prime factorization of 31 in exponential form is:

31 = 31¹

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 31 and 37.

LCM(31,37) = 31¹×37¹
LCM(31,37) = 1147

Factors of 31

List of positive integer factors of 31 that divides 31 without a remainder.

1, 31

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 31 and 37, than apply into the LCM equation.

GCF(31,37) = 1
LCM(31,37) = ( 31 × 37) / 1
LCM(31,37) = 1147 / 1
LCM(31,37) = 1147

(i) The LCM of 37 and 31 is associative

LCM of 31 and 37 = LCM of 37 and 31
