To sum up, the lcm of 4 and 18 is 36. In common notation: lcm (4,18) = 36.
What is the smallest number that has 1234 and five as factors?
Answer Expert Verified We can find that number by multiplying: 3 * 4 * 5 = 60. Therefore the smallest number that has 1, 2, 3, 4 and 5 as factors is 60.
What is the smallest number of factors?
The smallest number with a certain target number of divisors will always be a product of primorials. For example, the smallest number with exactly 11 divisors would be 210=1024.
Which is the smallest number with 12 factors?
On the other hand, four or more distinct prime factors (such as 2, 3, 5, and 7) will present us with with at least 2^4 choices and 2^4 = 16 divisors, which is more than we need. Now, since we can readily see that 2² X 3 X 5 = 60 is smaller than 2³ X 3² = 72, it is clear that 60 is the number we seek.
What is the smallest number that has three diferent prime factors?
The feedback you provide will help us show you more relevant content in the future. The smallest three prime numbers are 2, 3, 5. The smallest number that has three prime factors is the product of three smalles prime factors = 2*3*5=30.
Which is the smallest number with less than 9 divisors?
You can check this by asking how many divisors 72 has that are less than 9, the smallest positive integer whose square is greater than 72. It turns out that there are six, namely, 1, 2, 3, 4, 6, and 8.
What are factors and multiples in year 4?
Their knowledge of times tables should help them to work out that 24 is a multiple of 2, 8 and 6. Children also learn about factors in Year 4. They may be asked to identify pairs of factors of two-digit numbers. For example: they may be given the number 60 and asked to pick out two pairs of factors from the following numbers: 7, 3, 9, 8, 15, 4, 20.
