What numbers are divisable by 2 and 5?
As lcm(2, 5) = 10, all multiples of 10 are divisible by both 2 & 5.
When can the LCM of two numbers be one of those numbers?
The LCM of 2 numbers can be one of those numbers when the large of the 2 numbers is 2 times the smaller one of those numbers. For example the LCM of 2 and 4 is 4. For example the LCM of 5 and 10 is 10.
Numbers divisible by 2 and 5?
10 is the lcm
Can you find the least common multiple of two prime numbers?
Yes. For two prime numbers, the LCM is their product: one times the other. Multiply the two. (e.g. LCM of 5 and 7 is 35) By formula, the LCM for x and y is LCM = x * y / GCF and for primes, the GCF (greatest common factor) is 1.
What is the LCM of 10 and 5?
It is not possible to give a sensible answer to this question. The least common multiple (LCM) refers to a multiple that is COMMON to two or more numbers. You have only one number in the question!
What pair of numbers is the LCM of 5?
1 and 5 have an LCM of 5.
What is the LCM of numbers 1-10?
11
What is the LCM of 12 3 and 5?
1, and only 1. There are no common factors (whole numbers) between those three numbers but one.
What 2 numbers have the LCM of 30 and HCF of 1?
5 and 6
What two numbers have the LCM of 30 and the HCF of 1?
5 and 6
What two numbers have a LCM of30 and HCF of 1?
1 and 30 5 and 6
Why is 7 and 15 multiplied to get the LCM?
The factors of 15 is 3 and 5 i.e we get 15 by multiplying 3 and 5. All the three numbers are prime numbers ( they are divisible by only 1 and themselves). Hence the LCM can be only the product of 3, 5 and 7.
What is the LCM of 5 only?
You need at least two numbers to find an LCM.
What is the LCM of two numbers that have no common factors than 1 give an example?
The LCM of any two prime numbers is their product as for example the LCM of 5 and 7 is 35
What 3 numbers have a LCM of 25?
If all three numbers are different: 1, 5, 25. Otherwise, additionally one of the sets: {1, 1, 25}, {1, 25, 25}, {5, 5, 25}, {5, 25, 25}, {25, 25, 25}.
What is the least common multiple of 5 and 9?
The LCM of 5 and 9 is 45. The LCM is the product of all numbers divided by their highest common factor. 5 is prime, and 9 = 3 x 3 x 1, so the GCF is 1. Thus, the LCM is 5 x 9 = 45.45
What are two numbers whose GCF is 1 and LCM is 55?
11 and 5
