Least Common Multiple of 23 and 26

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

• Least Common Multiple of 23 and 26 by Prime method
• Least Common Multiple of 23 and 26 with GCF Formula

Least common multiple can be found by multiplying the highest exponent prime factors of 23 and 26. First we will calculate the prime factors of 23 and 26.

Prime Factorization of 23

Prime factors of 23 are 23. Prime factorization of 23 in exponential form is:

23 = 23¹

Prime Factorization of 26

Prime factors of 26 are 2,13. Prime factorization of 26 in exponential form is:

26 = 2¹×13¹

Now multiplying the highest exponent prime factors to calculate the LCM of 23 and 26.

LCM(23,26) = 2¹×13¹×23¹
LCM(23,26) = 598

Factors of 23

List of positive integer factors of 23 that divides 23 without a remainder.

1, 23

Factors of 26

List of positive integer factors of 26 that divides 26 without a remainder.

1, 2, 13, 26

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 23 and 26, than apply into the LCM equation.

GCF(23,26) = 1
LCM(23,26) = ( 23 × 26) / 1
LCM(23,26) = 598 / 1
LCM(23,26) = 598

(i) The LCM of 26 and 23 is associative
