Answer:
The least number of pennies the jar could contain is 840.
Explanation:
The least number of pennies the jar could contain refers to the Least Common Multiple (LCM) of 3, 4, 5, 6, 7, 8.
The least common multiple (LCM) of two or more numbers refers to the smallest number that is a multiple of all the numbers (except 0).
The LCM for 3, 4, 5, 6, 7, 8 can be obtained using the LCM function in Excel by inputting =LCM(3, 4, 5, 6, 7, 8) in any cell in an excel sheet (as done in the attached excel file).
From the attached excel file, we have:
LCM of 3, 4, 5, 6, 7, 8 = 840
Therefore, the least number of pennies the jar could contain is 840.
