LCM Prime Factorization
Enter whole numbers greater than 1.
RESULT
Common prime factors are underlined and written in green.
LCM is equal to the multiplication of the prime factors. But the common prime factors are multiplied only once.
DESCRIPTIONS

Prime factorization of 30 :
(30 = 2 × 3 × 5)
(Click here to see the prime factorization of 30 using the upside-down division method)
Common prime factors of 24 and 30 are 2, 3 and 3. LCM is equal to the product of the prime factors. But the common prime factors are multiplied only once.
LCM(24, 30) = 2 × 3 × 2 × 2 × 5 = 120

In addition to the cake method, we can calculate the LCM of two numbers by using prime factorization.
Once we find the prime factorization of the given numbers by using the factorization tree or the upside-down division method, we mark the common prime factors. In order to find the LCM, we multiply all prime factors but the common prime factors are used only once in the multiplication.
