Free LCM Calculator determines the least common multiple (LCM) between 10 and 60 the smallest integer that is 60 that is divisible by both numbers.
Least Common Multiple (LCM) of 10 and 60 is 60.
LCM(10,60) = 60
Least common multiple or lowest common denominator (LCD) can be calculated in three ways;
Least common multiple can be found by multiplying the highest exponent prime factors of 10 and 60. First we will calculate the prime factors of 10 and 60.

Factors of 60
List of positive integer factors of 60 that divides 60 without a remainder.
1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 10 and 60, than apply into the LCM equation.
GCF(10,60) = 10
LCM(10,60) = ( 10 × 60) / 10
LCM(10,60) = 600 / 10
LCM(10,60) = 60
(i) The LCM of 60 and 10 is associative
LCM of 10 and 60 = LCM of 60 and 10
