Answer: LCM the 4, 5, and 6 is 60.

Explanation:
The LCM of three non-zero integers, a(4), b(5), and also c(6), is the smallest hopeful integer m(60) the is divisible by a(4), b(5), and also c(6) without any type of remainder.
Let's look in ~ the different methods because that finding the LCM of 4, 5, and 6.
By Listing MultiplesBy division MethodBy prime Factorization MethodLCM that 4, 5, and 6 by Listing Multiples

To calculate the LCM of 4, 5, 6 by listing out the common multiples, we deserve to follow the given listed below steps:
Step 1: list a few multiples the 4 (4, 8, 12, 16, 20 . . .), 5 (5, 10, 15, 20, 25 . . .), and 6 (6, 12, 18, 24, 30 . . .).Step 2: The typical multiples native the multiples that 4, 5, and 6 room 60, 120, . . .Step 3: The smallest typical multiple the 4, 5, and also 6 is 60.∴ The least common multiple that 4, 5, and 6 = 60.
LCM the 4, 5, and 6 by division Method

To calculate the LCM the 4, 5, and 6 by the division method, we will divide the numbers(4, 5, 6) by their prime factors (preferably common). The product of this divisors offers the LCM the 4, 5, and 6.
Step 2: If any of the given numbers (4, 5, 6) is a lot of of 2, division it by 2 and write the quotient listed below it. Lug down any number that is not divisible by the element number.Step 3: continue the measures until just 1s room left in the last row.The LCM the 4, 5, and 6 is the product of all prime numbers on the left, i.e. LCM(4, 5, 6) by department method = 2 × 2 × 3 × 5 = 60.
LCM the 4, 5, and also 6 by element Factorization
Prime administrate of 4, 5, and also 6 is (2 × 2) = 22, (5) = 51, and also (2 × 3) = 21 × 31 respectively. LCM that 4, 5, and 6 deserve to be obtained by multiply prime determinants raised to your respective highest possible power, i.e. 22 × 31 × 51 = 60.Hence, the LCM of 4, 5, and 6 by prime factorization is 60.
