What is the least common multiple of 18 and 21?

The LCM of 18 and 21 is 126 because 18x7=126 and 21x6=126So if you need help finding LCM you take the 2 numbers and write down the multiples of both of those numbers and see which number they both go into.so here is how i got 12618,36,54,72,90,108,12621,42,63,84,105,126The least common multiple of 18 , 21 = 126


What is the lcm of 147 and 105?

Both of these numbers are divisible by 3 and 7. The factors of 105 is 21 x 5 and that of 147 is 21 x 7. So the LCM is 21 x 35 = 735.

What is tow LCM of 7 and 3?

To find the LCM of two numbers you need to multiply them together and then divide by the HCF. In this case, the numbers are coprime and so the HCF will be 1. Therefore was just have to multiply the numbers together: 7x3 = 21 And so the LCM of 7 and 3 is 21.
