Answer:
Look to the explanation
Step-by-step explanation:
- Multiples of a number are the numbers after multiplying the number
by an integer
- Ex: The multiples of 2 are 2 , 4 , 6 , 8 , .......... because 2 × 1 = 2 ,
2 × 4 = 4 , 2 × 3 = 6 and 2 × 4 = 8
- Factors of a number are the number multiplied together to get the
number
- Ex: The factors of 6 are 1 , 2 , 3 , 6 because 1 × 6 = 6 and 2 × 3 = 6
- Lowest common multiple of the set of numbers (LCM) is the
smallest number divisible by these numbers
- Ex: The lowest common multiple of 2 and 3 is 6 because 6 is divisible
by 2 and 3 and there is no number before it divisible by both
- Greatest common factor of the set of numbers (GCF) is the highest
common factor of these numbers
- Ex: The greatest common factor of 12 and 18 is 6 because
→ The factors of 12 are 1 , 2 , 3, 4, 6, 12
→ The factors of 18 are 1 , 2 , 3 , 6 , 9 , 18
→ The greatest common factor on both numbers is 6
