# Multiples & Factors

A Factor
A whole number that will divide exactly into another number. EXAMPLE: 8 is a factor of 24 because 3x8=24.
1 of 7
Factor Pairs
2 whole numbers that will multiply together to get a particular number. EXAMPLE: The factor pairs of 12 are 1&12, 2&6, 3&4.
2 of 7
Prime Numbers
A number that is only divisible by itself and 1. The prime numbers under 30 are: 2,3,5,7,11,13,17,19,23,29
3 of 7
Cube Numbers
The answer when a number is multiplied by itself and multipled by itself again. EXAMPLE: (3x3)x3=27
4 of 7
Highest Common Factor (HCF)
The largest out of all common factors of a number. EXAMPLE: Common factors of 8 and 12 are 1,2 and 4. HCF=4
5 of 7
Lowest Common Multiple (LCM)
A number that is a shared multiple of 2 or more numbers.EXAMPLE: 24 is a common multiple of 8&12. 8x3=24 12x2=24. It is found by listing the multiples of each number and circling any common ones. EXAMPLE: The LCM of 5 and 6=30. 5x6=30 6x5=30
6 of 7
Venn Diagrams
Show the relationship between different sets or catergories of data. EXAMPLE:if numbers 1,3,4,5,6,8,9,14,18 were being sorted by whether or not they were multiples of 3 or even numbers, 1&5= neither 4,8,14=even numbers 3&9=multiples of 3 6&18=both
