Given the sum 18=6+12 using their GCF and multiplication
To find the GCF (Greatest Common Factor) of 6 and 12, we need to list all the factors of the two numbers:
The factors of 6 are: 1, 2, 3, 6
The factors of 12 are: 1, 2, 3, 4, 6, 12
The common factors of 6 and 12 are: 1, 2, 3, 6
The highest common factor is 6.
To find the multiplication that gives a sum of 18, we can divide 18 by the GCF:
18 ÷ 6 = 3
Therefore, the multiplication that gives a sum of 18 is 6 multiplied by 3:
6 × 3 = 18
