The size of the largest square is 36m². To find for the measures of the squares, use the common factors of 42 and 60. Among the common factors, choose the greatest. Find the factors of 42 using the listing method. 42 - 1, 2, 3, 6, 7, 14, 21, 42 Find the factors of 60 using the listing method also. 60 - 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60 Identify the common factors of 42 and 60. 42 - 1, 2, 3, 6, 7, 14, 21, 42 60 - 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60 Common Factors: 1, 2, 3, 6 Therefore, the size of the largest square is 36m² since 6m x 6m is equals to 36m².
Answer: 1/2 times 6x equals 3x and then you do 1/2 times 4 and that equals 2 then multiply the 3 and 4 in the parenthesis and that is 12 then add 12 to the 3 and 2 and your answer is 17.
The least common multiple in this case is 4. The LCM is always ≥ the largest starting number, which is 4 for this example. Therefore, the statement is true.
