🐓 🦜🦩🐓 Common Factors and Common Multiples🐓 🦜🦩🐓
Welcome 👦👧boys and girls to another Mathematics class, today we will be exploring the topic common factors and Common multiples of numbers.
1. What are Common Factors?
A common factor is a whole number which is a factor of two or more numbers.
A factor is one of two or more numbers that divides into a number without a remainder.
Remember to find the common factors of two or more numbers. we have to first find the factors of the numbers.
A common factor- of two numbers are the factors shared or joint between two or more numbers.
🐭Examples:
What are the common factors of 6 and 12?
6={1, 2, 3, 6}
12= {1, 2, 3, 4, 6, 12}
Answer= the common factor of 6 and 8 are {1, 2, 3}
2. What are Common Multiples?
A common multiple is defined as a whole number, a shared multiple of each set of numbers.
A multiple- is a product that we get when one number is multiplied by another number.
A common multiple- of two numbers are the multiples shared or joint between two or more numbers.
🦋Example:
What are the multiples of 2 and 3?
4= { 4, 8, 12, 16, 20.....}
5={ 5, 10, 15, 20, 25....}
Answer= the multiples of 4 and 5 is {20}
