The highest common factor and the least common multiple of 432, 648, and 576 are _______________ and ______________, respectively.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 72, 5184.
The given values are 432, 648, and 576
The factors of these values
⇒ 432 = 24 × 33
⇒ 648 = 23 × 34
⇒ 576 = 26 × 32
Hence, the highest common factor = 23 × 32 = 8 × 9 = 72
and the least common factor = 26 × 34 = 64 × 81 = 5184
