Given numbers are 402,581,664,842

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

The LCM of 402,581,664,842 is 393318408.

Find LCM of 402,581,664,842 with Prime Factorization

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

2 x 83 x 201 x 7 x 4 x 421 = 393318408

Therefore, the lowest common multiple of 402,581,664,842 is 393318408.

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 581 x 664 x 842 = 130581711456

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

581 : 1, 7, 83, 581

664 : 1, 2, 4, 8, 83, 166, 332, 664

842 : 1, 2, 421, 842

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 402,581,664,842, is 1.

Now, the common factors can be found like this.

402:2x 3x 67

581:7x 83

664:2x 2x 2x 83

842:2x 421

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 83 = 332

Therefore, the value for common factors is 332.

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 = 130581711456/(1x332)

LCM = 130581711456/332

LCM = 393318408

Thus, we can understand that the LCM of 402,581,664,842 is 393318408.
