Given numbers are 513,817,919,209

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

The LCM of 513,817,919,209 is 222994431.

Find LCM of 513,817,919,209 with Prime Factorization

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

19 x 27 x 43 x 919 x 11 = 222994431

Therefore, the lowest common multiple of 513,817,919,209 is 222994431.

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.

513 x 817 x 919 x 209 = 80500989591

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.

513 : 1, 3, 9, 19, 27, 57, 171, 513

817 : 1, 19, 43, 817

919 : 1, 919

209 : 1, 11, 19, 209

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 513,817,919,209, is 1.

Now, the common factors can be found like this.

513:3x 3x 3x 19

817:19x 43

919:919

209:11x 19

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

19x 19 = 361

Therefore, the value for common factors is 361.

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 = 80500989591/(1x361)

LCM = 80500989591/361

LCM = 222994431

Thus, we can understand that the LCM of 513,817,919,209 is 222994431.
