20 and 40 have 4 and 5 as common factors.
4 and 5
They can be: 20 and 50 or 4 and 25
To simplify fractions, look for common factors - factors that are shared by both numbers, in this case, 4 and 8. If you find one, divide both numbers by the common factor. Repeat, until there are no more common factors.
The numbers 24 and 32 have 4 common factors, and they are 1, 2, 4 and 8, with 8 being the largest.
1 and 20 is one possible pair.
12 and 24
12 and 24
20 and 40
1, 2 and 4
These numbers, known as the common factors of 24 and 100, are:1, 2 and 4.
The first two common multiples of the pair of numbers 4 and 6 are: 12, 24.
All numbers have factors. Some numbers have some of the same factors as other numbers. These are common factors.
Since 1, known as the "multiplicative identity", cannot be counted as a factor, there are many pairs of numbers that do not have common factors, such as 2 and 3, 2 and 5, and 3 and 5. There are many pairs of composite (not prime) numbers without common factors, such as 4 and 9. Also, since prime numbers do not have factors, any pair of primes cannot have a common factor, though a pair in which one number is prime may, e.g. 5 and 10.
what are the common factors of 4 20 and 24
All nonzero numbers have factors. Some numbers have some of the same factors as other numbers. These are known as common factors.Common factors are factors that two or more numbers have in common. These are factors that are the same. All integers will have 1 as a common factor. Some integers will have additional common factors. For example, 4 and 6 have as their common factors 1 and 2.Numbers that evenly divide one or more numbersEx: 2 is a common factor for the numbers 4 and 6
4 and 5
How about: 3 and 4
