What is the LCM of 9 and 21? Answer: LCM of 9 and 21 is 63. Explanation: The LCM of two non-zero integers, x(9) and y(21), is the smallest positive integer m(63) that is divisible by both x(9) and y(21) without any remainder.
What are multiples of 9 and 21?
When we compare the two lists to see what they have in common, we get the answer to “What are the common multiples of 9 and 21?” 63, 126, 189, 252, etc. Since 63 is the first number they have in common, 63 is the least common multiple of 9 and 21.
What is the lowest common factor of 21 and 63?
To sum up, the lcm of 21 and 63 is 63. In common notation: lcm (21,63) = 63.
How to find the least common number of multiples?
There are multiple ways to find a least common multiple. The most basic is simply using a “brute force” method that lists out each integer’s multiples. EX: Find LCM (18, 26) 18: 18, 36, 54, 72, 90, 108, 126, 144, 162, 180, 198, 216, 234. 26: 52, 78, 104, 130, 156, 182, 208, 234.
Which is the least common multiple of 16 and 20?
LCM denotes the least common factor or multiple of any two or more given integers. For example, L.C.M of 16 and 20 will be 2 x 2 x 2 x 2 x 5 = 80, where 80 is the smallest common multiple for numbers 16 and 20. Now, if we consider the multiples of 16 and 20, we get; 16 → 16, 32, 48, 64, 80,…
Which is the least common multiple of 11 33?
We can see, the first common multiple or the least common multiple of both the numbers is 33. Hence, the LCM (11, 33) = 33. Another method to find the LCM of the given numbers is prime factorization. Suppose, there are three numbers 12, 16 and 24. Let us write the prime factors of all three numbers individually.
Which is the correct number for multiple of 5?
The multiples of 5 are the numbers which are generated when 5 is multiplied by any natural number. It can be represented as 5n, where n = 1, 2, 3, 4, 5, …and so on.
