A factor of a number is an exact divisor of that number i.e. the factor leaves remainder 0 when it divides the number.Multiples are what we get after multiplying the number by an integer (not a fraction). Watch Factors and Multiples Videos to learn more.
A factor of a number is an exact divisor of that number i.e. the factor leaves remainder 0 when it divides the number.
For example : 4 × 5 = 20
4 and 5 are factors of 20. We can also say that 20 is multiple of 4 and 5.
In 2 × 12 = 24,
2 and 12 are factors of 24.
COMMON FACTORS are: Factors that two or more numbers have in common . The greatest factor that both numbers have in common.
Start with 1 x the number. Try 2, 3, 4, etc. When you repeat your factors, cross out the repeat – you’re done at this point. If you get doubles (such as 4 x 4), then you’re done. Repeats or doubles let you know you’re done.
A multiple is the product of a given whole number and another whole number.
Multiples form a skip counting pattern. For example:
5: 5, 10, 15, 20, 25, 30…
Common Multiple :
A multiple that 2 or more numbers have in common.
Least Common Multiple :
The smallest multiple that 2 or more numbers have in common.
