Answer:
a. 24 is a common multiple, but not the least common multiple
Explanation:
To check which statement is true, we need to follow the steps below;
First, lets find the multiples of 4 and then multiples of 6
Multiples of 4 = 4, 8, 12, 16, 20, 24, 28.....................................................
Multiples of 6 =6, 12, 18, 24, 32 ................................................................
Common multiples of 4 and 6 are 12, 24
The least common multiples of 4 and 6 is 12
Therefore 24 is a common multiple of 4 and 6 but its not the least common multiple of 4 and 6 rather 12 is the least common multiple of 4 and 6.
Next lets find the factors of 4 and 6
Factors of 4 = 1, 2, 4
Factors of 6 = 1, 2, 3, 6.
Common factors of 4 and 6= 1, 2
Greatest common factor of 4 and 6 = 2
Therefore, 24 is also not the greatest common factors of 4 and 6 but rather 2 is the greatest common factor.
Therefore the only true statements of Aram is option a. 24 is a common multiple, but not the least common multiple
