Given numbers are 663,391,391,743

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

The LCM of 663,391,391,743 is 11330007.

Find LCM of 663,391,391,743 with Prime Factorization

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

17 x 23 x 39 x 1 x 1 x 743 = 11330007

Therefore, the lowest common multiple of 663,391,391,743 is 11330007.

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.

663 x 391 x 391 x 743 = 75310556529

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.

663 : 1, 3, 13, 17, 39, 51, 221, 663

391 : 1, 17, 23, 391

391 : 1, 17, 23, 391

743 : 1, 743

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 663,391,391,743, is 1.

Now, the common factors can be found like this.

663:3x 13x 17

391:17x 23

391:17x 23

743:743

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

17x 17x 23 = 6647

Therefore, the value for common factors is 6647.

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 = 75310556529/(1x6647)

LCM = 75310556529/6647

LCM = 11330007

Thus, we can understand that the LCM of 663,391,391,743 is 11330007.
