Question

10. Find out the common multiples of 5 and 6. Write the smallest multiple.​

Answer 1

Answer:

5:5,10,15,20,25,30,35,40,45,50,55,60....

6: 6,12,18,24,30,36,42,48,54,60,..

Answer 2

Answer:

multiples of a number are the numbers seen in their times tables

so the multiples of

5: {5,10,15,20,25,30,35,40,45,50,55,60.....}

multiples of

6: {6,12,18,24,30,36,42,48,54,60,....}

the common multiples are those which appear in BOTH lists

in this case

{30,60,...}

(can you work out the next one?)

so the smallest, ie lowest common multiple

lcm(5,6)=30
