Least Common Multiple of 93 and 97

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

• Least Common Multiple of 93 and 97 by Prime method
• Least Common Multiple of 93 and 97 with GCF Formula

Least common multiple can be found by multiplying the highest exponent prime factors of 93 and 97. First we will calculate the prime factors of 93 and 97.

Prime Factorization of 93

Prime factors of 93 are 3,31. Prime factorization of 93 in exponential form is:

93 = 3¹×31¹

Prime Factorization of 97

Prime factors of 97 are 97. Prime factorization of 97 in exponential form is:

97 = 97¹

Now multiplying the highest exponent prime factors to calculate the LCM of 93 and 97.

LCM(93,97) = 3¹×31¹×97¹
LCM(93,97) = 9021

Factors of 93

List of positive integer factors of 93 that divides 93 without a remainder.

1, 3, 31, 93

Factors of 97

List of positive integer factors of 97 that divides 97 without a remainder.

1, 97

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 93 and 97, than apply into the LCM equation.

GCF(93,97) = 1
LCM(93,97) = ( 93 × 97) / 1
LCM(93,97) = 9021 / 1
LCM(93,97) = 9021

(i) The LCM of 97 and 93 is associative
