Answer:
Least positive integer divisible by the numbers 2, 4, and 7 is  28
Step-by-step explanation:
We can find the least positive integer divisible by the numbers 2, 4, and 7 by taking the LCM
First lets List all prime factors for each number.
Prime Factorization of 2
2 is prime  =>  
Prime Factorization of 4 is:
2 x 2  =>  
Prime Factorization of 7 is:
7 is prime  => 
For each prime factor, find where it occurs most often as a factor and write it that many times in a new list.
The new superset list is
2, 2, 7
Multiply these factors together to find the LCM.
LCM = 2 x 2 x 7 = 28
