Given numbers are 642,759,520,351,555

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

The LCM of 642,759,520,351,555 is 14062843080.

Find LCM of 642,759,520,351,555 with Prime Factorization

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

2 x 3 x 5 x 13 x 107 x 253 x 4 x 9 x 37 = 14062843080

Therefore, the lowest common multiple of 642,759,520,351,555 is 14062843080.

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.

642 x 759 x 520 x 351 x 555 = 49360579210800

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.

642 : 1, 2, 3, 6, 107, 214, 321, 642

759 : 1, 3, 11, 23, 33, 69, 253, 759

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

351 : 1, 3, 9, 13, 27, 39, 117, 351

555 : 1, 3, 5, 15, 37, 111, 185, 555

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,759,520,351,555, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

759:3x 11x 23

520:2x 2x 2x 5x 13

351:3x 3x 3x 13

555:3x 5x 37

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

2x 3x 3x 3x 5x 13 = 3510

Therefore, the value for common factors is 3510.

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 = 49360579210800/(1x3510)

LCM = 49360579210800/3510

LCM = 14062843080

Thus, we can understand that the LCM of 642,759,520,351,555 is 14062843080.
