Given numbers are 403,557,646,408,624

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

The LCM of 403,557,646,408,624 is 3480198384.

Find LCM of 403,557,646,408,624 with Prime Factorization

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

2 x 2 x 2 x 3 x 13 x 17 x 31 x 557 x 19 x 1 x 2 = 3480198384

Therefore, the lowest common multiple of 403,557,646,408,624 is 3480198384.

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.

403 x 557 x 646 x 408 x 624 = 36917944457472

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.

403 : 1, 13, 31, 403

557 : 1, 557

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

408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408

624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,557,646,408,624, is 1.

Now, the common factors can be found like this.

403:13x 31

557:557

646:2x 17x 19

408:2x 2x 2x 3x 17

624:2x 2x 2x 2x 3x 13

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

2x 2x 2x 2x 3x 13x 17 = 10608

Therefore, the value for common factors is 10608.

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 = 36917944457472/(1x10608)

LCM = 36917944457472/10608

LCM = 3480198384

Thus, we can understand that the LCM of 403,557,646,408,624 is 3480198384.
