Six.

It is the lowest number that has the first ten counting numbers as factors.

All factors of 25 and 4 are lowest common multiples of some numbers. Factors of 25: 1, 5, 25 Factors of 4: 1, 2, 4 eg 25 is lcm of 5 and 25. The only (and thus) lowest common factor of 25 and 4 is 1. Thus the lowest common multiple of 25 and 4 is 100.

To find the lowest common multiple of 4, 6 and 11 you first need to break these numbers down into their prime factors: 4 = 2x2 6 = 2x3 11 = 11 The next step is to identify any common factors. In this case two numbers have a 2 as a prime factor, so we can discard one of these. Take all the other prime factors (2, 2, 3 and 11) and multiply them together: 2x2x3x11 = 132. Thus the lowest common multiple of 4, 6 and 11 is 132.

Prime numbers have exactly two factors. 3 has exactly two factors: 1 and 3. So 3 is prime. Composite numbers have more than two factors. 4 is composite because it has three factors: 1, 2, and 4.

The LCM refers to whole numbers, not decimals.

they are called numbers with 3 factors

To work out the lowest common multiple of two or more numbers we need to resolve each number to its prime factors. Then, we can multiply those factors together to give us the lowest common multpile. The factors of 4 are 2, 2 The factors of 4 are 2, 3 To be a multiple of 4, the lowest common multiple must have 2 and 2 in its list to be a multiple of 4, the lowest common multiple must have 2 and 3 in its list So, starting with the 4 we have (2, 2) As there is already a 2 in the mix, when we come to the 6 we only need to add the 3 making our list (2, 2, 3) If we multiple all these numbers together we get 12. 4 x 3 = 12 6 x 2 = 12

4, with factors 1, 2 and 4

All factors of 25 and 4 are lowest common multiples of some numbers. Factors of 25: 1, 5, 25 Factors of 4: 1, 2, 4 eg 25 is lcm of 5 and 25. The only (and thus) lowest common factor of 25 and 4 is 1. Thus the lowest common multiple of 25 and 4 is 100.

Look for common factors in the two numbers. Divide both numbers by the common factors. Continue until there are no more common factors.
