Given numbers are 663,119,591,391

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

The LCM of 663,119,591,391 is 21028371.

Find LCM of 663,119,591,391 with Prime Factorization

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

3 x 17 x 13 x 7 x 197 x 23 = 21028371

Therefore, the lowest common multiple of 663,119,591,391 is 21028371.

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 119 x 591 x 391 = 18231597657

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

119 : 1, 7, 17, 119

591 : 1, 3, 197, 591

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 663,119,591,391, is 1.

Now, the common factors can be found like this.

663:3x 13x 17

119:7x 17

591:3x 197

391:17x 23

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

3x 17x 17 = 867

Therefore, the value for common factors is 867.

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 = 18231597657/(1x867)

LCM = 18231597657/867

LCM = 21028371

Thus, we can understand that the LCM of 663,119,591,391 is 21028371.
