Answer :
Answer:
105
Step-by-step explanation:
First of all this is to easy if you don't know how to do this then your in danger of math and you should ask your math teacher for private online lesson regarding this.
LCM of 15,21
3 | 15 | 21
5 | 5 | 7
7 | 1 | 7
| 1 | 1
LCM: 3x5x7 -> 105
Answer: The answer to this math question about finding The Lowest Common Multiple (LCM) of the given pairs for #15 and #21 is 105.
Step-by-step explanation: So, according to the online calculator website is called, "Calculatorsoup.com", I chose to find another option is called, " Greatest Common Factor Method (GCF Method)" of the given with the pairs of the numbers, so anyways, here are the following steps in order to find The Greatest Common Factor Method (GCF Method) with the given following pairs #15 and #21 are being shown below here:
Step 1. First, find The Greatest Common Factor of 15 and 21: The answer is 3 that looks in the equation form like this: [tex]LCM(15,21) = \frac{(15*21)}{GCF(15,21)}.[/tex]
Step 2. Next, after finding The Greatest Common Factor of 15 and 21 from step #1, let's multiply the given pairs of the numbers in the brackets first, and then divide by 3 from The Greatest Common Factor that has already been found that looks in the equation form like this: [tex]\frac{(15 * 21)}{3}.[/tex]
Step 3. Then, after multiplying the given pairs of the numbers in the brackets first from step #2, let's divide by 3 from The Greatest Common Factor that has already been found that looks in the equation form like this: [tex]\frac{315}{3}.[/tex]
Step 4. Finally, after dividing by 3 from The Greatest Common Factor that has already been found, here is your answer to this math question about finding The Lowest Common Multiple of the given pairs for #15 and #21 that looks in the equation form like this: [tex]LCM(15, 21) = 105.[/tex]
I hoped that my given answer with my given explanation is very helpful to your own math question about finding The Lowest Common Multiple (LCM) of the given pairs for #15 and #21, also using my new given hint to find The Greatest Common Factor of the given pairs of the numbers is also helpful to your own math question as well according to the online calculator website is called, "Calculatorsoup.com", that's all for today, please mark me as Brainliest and have a great rest of the day! :D
