Given numbers are 411,143,638,209

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

The LCM of 411,143,638,209 is 64767846.

Find LCM of 411,143,638,209 with Prime Factorization

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

11 x 411 x 13 x 58 x 19 = 64767846

Therefore, the lowest common multiple of 411,143,638,209 is 64767846.

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.

411 x 143 x 638 x 209 = 7836909366

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.

411 : 1, 3, 137, 411

143 : 1, 11, 13, 143

638 : 1, 2, 11, 22, 29, 58, 319, 638

209 : 1, 11, 19, 209

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 411,143,638,209, is 1.

Now, the common factors can be found like this.

411:3x 137

143:11x 13

638:2x 11x 29

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.

11x 11 = 121

Therefore, the value for common factors is 121.

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 = 7836909366/(1x121)

LCM = 7836909366/121

LCM = 64767846

Thus, we can understand that the LCM of 411,143,638,209 is 64767846.
