Question

Jodie bought some shirts for $6 each. Marge bought some shirts for $8 each. What was the least amount they could have spent

Answer 1

Least amount they would spend is $40

Explanation:

Given:

Jodie bought some shirts for $6 each

Marge Bought some shirts for $8 each

To Find:

Least Money they spent = ?

Solution:

Least money they would spent would be the LCM of the values which means that the least common multiple of the values

so for finding the LCM we will make prime factors of both values we have

Now

Factors of 6 = 2 * 3

Factors of 8 = 2*2*2

Common Factor = 2

Remaining factors = 3,2,2

Now

LCM = Common factor * remaining factor

So

LCM = 2*3*2*2

= 40

SO their LCM is 40

Which means that least value they would spend would be $40
