Given numbers are 571,460,230,21

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

The LCM of 571,460,230,21 is 5515860.

Find LCM of 571,460,230,21 with Prime Factorization

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

2 x 5 x 23 x 571 x 2 x 1 x 21 = 5515860

Therefore, the lowest common multiple of 571,460,230,21 is 5515860.

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.

571 x 460 x 230 x 21 = 1268647800

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.

571 : 1, 571

460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460

230 : 1, 2, 5, 10, 23, 46, 115, 230

21 : 1, 3, 7, 21

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 571,460,230,21, is 1.

Now, the common factors can be found like this.

571:571

460:2x 2x 5x 23

230:2x 5x 23

21:3x 7

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

2x 5x 23 = 230

Therefore, the value for common factors is 230.

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 = 1268647800/(1x230)

LCM = 1268647800/230

LCM = 5515860

Thus, we can understand that the LCM of 571,460,230,21 is 5515860.
