User: what is the least common multiple of 30 and 42

User: define the least common multiple

User: what is the least common multiple of 30 and 42 and why?







Weegy: what is the least common multiple of 30 and 42 and why? Answer: The least common multiple is 210. The prime factors of 30 are 2, 3, and 5. The prime factors of 42 are 2, 3, [ and 7. The prime factors in common are 2 and 3. The least common multiple is (2 x 3 x 5) x (2 x 3 x 7) / (2 x 3) = 210. By representing it as a calculation with prime factors, you can cancel out the divisors, so you have as your reduced calculation 5 x 2 x 3 x 7 rather than 30 x 42 ÷ 6. ]

starting with 1, how far do you have to go to get all the factors of a number?
Weegy: Begin the list with 1, leave some space for other numbers, and end the list with the number itself. Test whether 2 is a factor — that is, see whether the number is divisible by 2. If it is, add 2 to the list, [ along with the original number divided by 2 as the second-to-last number on the list. Test the number 3 in the same way. Continue testing numbers until the beginning of the list meets the end of the list. ] (More)
