Given numbers are 638,351,796,884

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

The LCM of 638,351,796,884 is 1515164508.

Find LCM of 638,351,796,884 with Prime Factorization

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

2 x 2 x 13 x 319 x 27 x 199 x 17 = 1515164508

Therefore, the lowest common multiple of 638,351,796,884 is 1515164508.

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.

638 x 351 x 796 x 884 = 157577108832

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.

638 : 1, 2, 11, 22, 29, 58, 319, 638

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

796 : 1, 2, 4, 199, 398, 796

884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,351,796,884, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

351:3x 3x 3x 13

796:2x 2x 199

884:2x 2x 13x 17

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 13 = 104

Therefore, the value for common factors is 104.

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 = 157577108832/(1x104)

LCM = 157577108832/104

LCM = 1515164508

Thus, we can understand that the LCM of 638,351,796,884 is 1515164508.
