### LCM of 10 and 15 by Division Method

To calculate the LCM of 10 and 15 using the division method, we divide the numbers (10, 15) by their prime factors (preferably common). The product of these divisors for the LCM is 10 and 15.

**Step 1:**Find the smallest prime that is a factor of at least one of the numbers 10 and 15. Write this prime (2) to the left of the given numbers (10 and 15), separated by a ladder arrangement.**Step 2:**If a given number (10, 15) is a multiple of 2 then divide it by 2 and write the quotient below. Bring down any number that is not divisible by primes.**Step 3:**Continue the steps until there are only 1s left in the last row.

The LCM of 10 and 15 is the product of all the primes to the left, i.e. LCM (10, 15) by division = 2 × 3 × 5 = 30.
