Question

Mrs. Smith has bolts of material that have lengths of 42, 63, and 105 inches. She needs to cut the fabric into equal length pieces with none left over. What is the greatest length of fabric pieces she can cut?

Answer 1

for this question, you just have to go back to the basics and list out the factors and see which ones work for all three... also, the question shows that it is a gcf problem because of the words equal length pieces, and greatest length of fabric pieces and it deals with three separate lengths
42 63 105
1--------------1------------1
2
3--------------3------------3
4 5
6
7--------------7-------------7
14
21------------21-----------21

Therefore, 21 is the answer, because it is the highest factor to work for all three numbers
