Given numbers are 654,345,845,409

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

The LCM of 654,345,845,409 is 5198590410.

Find LCM of 654,345,845,409 with Prime Factorization

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

3 x 5 x 218 x 23 x 169 x 409 = 5198590410

Therefore, the lowest common multiple of 654,345,845,409 is 5198590410.

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.

654 x 345 x 845 x 409 = 77978856150

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.

654 : 1, 2, 3, 6, 109, 218, 327, 654

345 : 1, 3, 5, 15, 23, 69, 115, 345

845 : 1, 5, 13, 65, 169, 845

409 : 1, 409

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 654,345,845,409, is 1.

Now, the common factors can be found like this.

654:2x 3x 109

345:3x 5x 23

845:5x 13x 13

409:409

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

3x 5 = 15

Therefore, the value for common factors is 15.

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 = 77978856150/(1x15)

LCM = 77978856150/15

LCM = 5198590410

Thus, we can understand that the LCM of 654,345,845,409 is 5198590410.
