Given numbers are 402,798,642,331

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

The LCM of 402,798,642,331 is 1893605322.

Find LCM of 402,798,642,331 with Prime Factorization

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

2 x 3 x 67 x 133 x 107 x 331 = 1893605322

Therefore, the lowest common multiple of 402,798,642,331 is 1893605322.

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.

402 x 798 x 642 x 331 = 68169791592

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.

402 : 1, 2, 3, 6, 67, 134, 201, 402

798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798

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

331 : 1, 331

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 402,798,642,331, is 1.

Now, the common factors can be found like this.

402:2x 3x 67

798:2x 3x 7x 19

642:2x 3x 107

331:331

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 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 68169791592/(1x36)

LCM = 68169791592/36

LCM = 1893605322

Thus, we can understand that the LCM of 402,798,642,331 is 1893605322.
