Least Common Multiple of 6 and 26

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

• Least Common Multiple of 6 and 26 by Prime method
• Least Common Multiple of 6 and 26 with GCF Formula

Least common multiple can be found by multiplying the highest exponent prime factors of 6 and 26. First we will calculate the prime factors of 6 and 26.

Prime Factorization of 6

Prime factors of 6 are 2,3. Prime factorization of 6 in exponential form is:

6 = 2¹×3¹

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 6 and 26.

LCM(6,26) = 2¹×3¹×13¹
LCM(6,26) = 78

Factors of 6

List of positive integer factors of 6 that divides 6 without a remainder.

1, 2, 3, 6

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 6 and 26, than apply into the LCM equation.

GCF(6,26) = 2
LCM(6,26) = ( 6 × 26) / 2
LCM(6,26) = 156 / 2
LCM(6,26) = 78

(i) The LCM of 26 and 6 is associative
