Divide each one out to see which is cheaper. 4.39/12 = .37 cents per pint while 2.89/8 = .36 cents per pint. These are cost per unit problems.The second choice is the cheaper of 2 by a cent.
The least common multiple is the smallest term that can be divided to both terms without any remainder. For the two terms 8c^4 and 6c^2, you can determine it into two part. First, you find the LCM for 8 and 6. You find the prime number that is common between the two. That would be 2. For the variables c^4 and c^2, the 'prime variable' is c. Therefore, the least common multiple for 8c^4 and 6c^2 is 2c.
