Common Division Method To Find LCM of 8 and 15
In this division method, we divide the numbers simultaneously with prime numbers and stop it when we don't have a prime number to divide the given numbers.
Empirical Formula To Find LCM of 8 and 15
The formula of LCM is LCM (a,b) = (a × b) / GCF (a,b)
The greatest common factor of (8, 15) = 1
So, by incorporating all the values, we get
LCM of 8 and 15 = (8 × 15) / 1
= 120/1 = 120
LCM of 8 and 15 = 120
LCM of 8 and 15 is the same, whichever method we opt for finding the least common multiple.
