Question

Veena has some beads. She wants to make necklaces with an equal number of beads in each. If she makes necklaces of 16 or 24 or 40 beads, there is no bead left over. What is the least number of beads with her?

Answer 1

the number of beads that she has is a common multiple of all the three numbers i . e . 16 , 24 and 40.
lcm of 16 , 24 and 40 is 240
hence she has 240 beads with her.

Answer 2

Answer:

240

Step-by-step explanation:

Given Veena has some beads. She wants to make necklaces with an equal number of beads in each. If she makes necklaces of 16 or 24 or 40 beads, there is no bead left over. What is the least number of beads with her?

Now Veena has some beads . She wants to make necklace out of it. So we need to find the least number of beads she requires to make the necklace. So we need to find the LCM (least common multiple) of the given three numbers.

We have 16, 24 and 40.

  So factors of 16, 24 and 40 are 2 x 2 x 2 x 2 x 3 x 5 = 240

So the least number of beads with her is 240
