Answer:

112

Explanation:

Find the lowest common multiple of 14 and 16.

To find the lowest common multiple:

1) Break the numbers down into their prime factors.

14 =
2^(1) x
7^(1)

16 = 2 x 8 = 2 x 2 x 4 = 2 x 2 x 2 x 2 =
2^(4)

2) Multiply the highest power of each prime number.

We have three numbers, but only two are unique:
2^(1) ,
7^(1) and
2^(4)


2^(4) >
2^(1) , so we will use
2^(4)


7^(1) x
2^(4) = 7 x 16 = 112
