Given numbers are 411,434,377,646

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

The LCM of 411,434,377,646 is 21720780354.

Find LCM of 411,434,377,646 with Prime Factorization

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

2 x 411 x 217 x 377 x 323 = 21720780354

Therefore, the lowest common multiple of 411,434,377,646 is 21720780354.

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 434 x 377 x 646 = 43441560708

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

434 : 1, 2, 7, 14, 31, 62, 217, 434

377 : 1, 13, 29, 377

646 : 1, 2, 17, 19, 34, 38, 323, 646

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 411,434,377,646, is 1.

Now, the common factors can be found like this.

411:3x 137

434:2x 7x 31

377:13x 29

646:2x 17x 19

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

2 = 2

Therefore, the value for common factors is 2.

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 = 43441560708/(1x2)

LCM = 43441560708/2

LCM = 21720780354

Thus, we can understand that the LCM of 411,434,377,646 is 21720780354.
