Final answer:
The least common multiple (LCM) of 12 and 7 is 84, which is the product of the two numbers since 7 is prime and not a factor of 12.
Step-by-step explanation:
The question is asking to find the least common multiple (LCM) of 12 and 7. To find the LCM of two numbers, we look for the smallest number that both original numbers can divide into without leaving a remainder.
Since 7 is a prime number and 12 does not have 7 as a factor, the LCM will simply be the product of the two numbers. Therefore, the LCM of 12 and 7 is 12 × 7, which equals 84. This means that the least common multiple of 12 and 7 is 84.
