Given numbers are 398,578,866,669

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

The LCM of 398,578,866,669 is 33319227894.

Find LCM of 398,578,866,669 with Prime Factorization

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

2 x 199 x 289 x 433 x 669 = 33319227894

Therefore, the lowest common multiple of 398,578,866,669 is 33319227894.

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.

398 x 578 x 866 x 669 = 133276911576

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.

398 : 1, 2, 199, 398

578 : 1, 2, 17, 34, 289, 578

866 : 1, 2, 433, 866

669 : 1, 3, 223, 669

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,578,866,669, is 1.

Now, the common factors can be found like this.

398:2x 199

578:2x 17x 17

866:2x 433

669:3x 223

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 133276911576/(1x4)

LCM = 133276911576/4

LCM = 33319227894

Thus, we can understand that the LCM of 398,578,866,669 is 33319227894.

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