All the numbers up to 100 are factors in some numbers up to 100. For example, 1 is a factor of every number and 2 is a factor of all the even numbers. The numbers greater than 50 are only factors of themselves among the numbers up to 100, 95 is only a factor of itself, because the next number for which it is a factor is 190, which is greater than 100.
To find the highest common factor of two numbers you first need to break them down into their prime factors. In this case: 24 = 2x2x2x3 28 = 2x2x7 The next step is to identify the common factors. In this case, both numbers have two 2s as a factor. We multiply these together to get the HCF: 2x2=4 Thus 4 is the highest common factor of 24 and 28.
To work this out, you first have to break the two numbers into their prime factors: 50 = 2x5x5 54 = 2x3x3 The next step is to identify any common prime factors. In this case both numbers have a 2 as a prime factor. Therefore the GCF of 50 and 54 is 2.
The ladder method, also known as the ladder division method, is a technique used to find the greatest common factor (GCF) of multiple numbers. To use the ladder method for 3 numbers, you would typically write the numbers at the top of three separate columns. Then, you would find the prime factors of each number and list them in a column beneath. Next, you would circle the common factors in each column and multiply them to find the GCF. Repeat this process until you have no common factors left.
There can be no such number. Suppose x is the least common multiple (LCM) of these numbers. Then 2*LCM is also a common multiple and is greater. And then 3*LCM is a common multiple and greater still. And so on, for ever.
Numbers that have only two factors are prime numbers. You're looking for the next three prime numbers over a certain number. But, you didn't tell us what number the three numbers have to be greater than.
7, 9, 11
The numbers with only three factors are squares of prime numbers.
The next three primes greater than 41 are 43, 47, and 53.
42 and its next three multiples.
The only numbers which have exactly three factors are perfect squares of prime numbers. That only gives us two results: 5^2 = 25 7^2 = 49 The squares of any other prime numbers are either too small or too large to have two digits. (The next smaller prime number is 3, and the next larger prime number is 11.)
the next three numbers are 180 540 and 1620=)
The difference between the successive numbers is 4. so the next three numbers could be 4, 0 and -4.
all numbers greater than 5.5
The number 9: factors are 9, 3, and 1.
Adding 0.6 each time gives 5.2, 5.8 and 6.4 as the next three numbers.
There are an infinity of such numbers. The next few are 9, 11, 13.
