Given numbers are 617,645,412,206

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

The LCM of 617,645,412,206 is 163961580.

Find LCM of 617,645,412,206 with Prime Factorization

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

2 x 103 x 617 x 645 x 2 x 1 = 163961580

Therefore, the lowest common multiple of 617,645,412,206 is 163961580.

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.

617 x 645 x 412 x 206 = 33776085480

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.

617 : 1, 617

645 : 1, 3, 5, 15, 43, 129, 215, 645

412 : 1, 2, 4, 103, 206, 412

206 : 1, 2, 103, 206

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 617,645,412,206, is 1.

Now, the common factors can be found like this.

617:617

645:3x 5x 43

412:2x 2x 103

206:2x 103

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

2x 103 = 206

Therefore, the value for common factors is 206.

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 = 33776085480/(1x206)

LCM = 33776085480/206

LCM = 163961580

Thus, we can understand that the LCM of 617,645,412,206 is 163961580.
