Question

A jewelry maker will use 24 jade beads and 30 teak to make necklace. Each necklace will have the same numbers of jade beads and teak beads. What is the greatest number of necklace she can make? how many beads of each type are on each necklace?

Answer 1

Greatest number would be Their "Greatest Common Factor" (GCD)
We know, 24 = 6 * 4 & 30 = 6 * 5

So, GCD = 6

In short, She can make 6 necklaces.
4 jade beads & 5 teaks on each necklace

Hope this helps!
