Given numbers are 391,814,402,698

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

The LCM of 391,814,402,698 is 22326602826.

Find LCM of 391,814,402,698 with Prime Factorization

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

2 x 391 x 407 x 201 x 349 = 22326602826

Therefore, the lowest common multiple of 391,814,402,698 is 22326602826.

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.

391 x 814 x 402 x 698 = 89306411304

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.

391 : 1, 17, 23, 391

814 : 1, 2, 11, 22, 37, 74, 407, 814

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

698 : 1, 2, 349, 698

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,814,402,698, is 1.

Now, the common factors can be found like this.

391:17x 23

814:2x 11x 37

402:2x 3x 67

698:2x 349

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 89306411304/(1x4)

LCM = 89306411304/4

LCM = 22326602826

Thus, we can understand that the LCM of 391,814,402,698 is 22326602826.
