Given numbers are 579,551,718,21

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

The LCM of 579,551,718,21 is 1603439754.

Find LCM of 579,551,718,21 with Prime Factorization

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

3 x 193 x 551 x 718 x 7 = 1603439754

Therefore, the lowest common multiple of 579,551,718,21 is 1603439754.

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.

579 x 551 x 718 x 21 = 4810319262

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.

579 : 1, 3, 193, 579

551 : 1, 19, 29, 551

718 : 1, 2, 359, 718

21 : 1, 3, 7, 21

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 579,551,718,21, is 1.

Now, the common factors can be found like this.

579:3x 193

551:19x 29

718:2x 359

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.

3 = 3

Therefore, the value for common factors is 3.

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 = 4810319262/(1x3)

LCM = 4810319262/3

LCM = 1603439754

Thus, we can understand that the LCM of 579,551,718,21 is 1603439754.
