Given numbers are 717,623,440,399

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

The LCM of 717,623,440,399 is 3734336760.

Find LCM of 717,623,440,399 with Prime Factorization

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

3 x 7 x 239 x 89 x 440 x 19 = 3734336760

Therefore, the lowest common multiple of 717,623,440,399 is 3734336760.

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.

717 x 623 x 440 x 399 = 78421071960

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.

717 : 1, 3, 239, 717

623 : 1, 7, 89, 623

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

399 : 1, 3, 7, 19, 21, 57, 133, 399

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 717,623,440,399, is 1.

Now, the common factors can be found like this.

717:3x 239

623:7x 89

440:2x 2x 2x 5x 11

399:3x 7x 19

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

3x 7 = 21

Therefore, the value for common factors is 21.

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 = 78421071960/(1x21)

LCM = 78421071960/21

LCM = 3734336760

Thus, we can understand that the LCM of 717,623,440,399 is 3734336760.

Here are some samples of LCM of two or more Numbers calculations.
