Answer: LCM that 3 and 5 is 15.
Explanation:
The LCM of two non-zero integers, x(3) and also y(5), is the smallest hopeful integer m(15) the is divisible by both x(3) and y(5) without any type of remainder.
Let's look at the various methods for finding the LCM of 3 and also 5.
By department MethodBy Listing MultiplesBy element Factorization MethodLCM that 3 and 5 by department Method
To calculate the LCM of 3 and 5 by the department method, we will certainly divide the numbers(3, 5) by your prime factors (preferably common). The product of this divisors gives the LCM the 3 and 5.
Step 3: continue the steps until just 1s room left in the last row.The LCM the 3 and 5 is the product of all prime number on the left, i.e. LCM(3, 5) by division method = 3 × 5 = 15.
LCM the 3 and 5 by Listing Multiples
To calculate the LCM of 3 and 5 through listing out the typical multiples, we can follow the given below steps:
Step 1: list a couple of multiples that 3 (3, 6, 9, 12, 15, 18, 21, . . . ) and 5 (5, 10, 15, 20, 25, 30, 35, . . . . )Step 2: The common multiples native the multiples that 3 and also 5 room 15, 30, . . .Step 3: The smallest common multiple the 3 and also 5 is 15.∴ The least common multiple of 3 and 5 = 15.
LCM of 3 and also 5 by element Factorization
Prime administrate of 3 and 5 is (3) = 31 and also (5) = 51 respectively. LCM of 3 and also 5 deserve to be acquired by multiplying prime determinants raised to your respective highest possible power, i.e. 31 × 51 = 15.Hence, the LCM the 3 and 5 by element factorization is 15.
