Given numbers are 21,834,343

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 21,834,343 is 286062.

Find LCM of 21,834,343 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

3 x 7 x 1 x 278 x 49 = 286062

Therefore, the lowest common multiple of 21,834,343 is 286062.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

21 x 834 x 343 = 6007302

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

21 : 1, 3, 7, 21

834 : 1, 2, 3, 6, 139, 278, 417, 834

343 : 1, 7, 49, 343

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 21,834,343, is 1.

Now, the common factors can be found like this.

21:3x 7

834:2x 3x 139

343:7x 7x 7

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

3x 7 = 21

Therefore, the value for common factors is 21.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 6007302/(1x21)

LCM = 6007302/21

LCM = 286062

Thus, we can understand that the LCM of 21,834,343 is 286062.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 43, 989, 124
• LCM of 65, 176, 918
