Given numbers are 402,661,406,204

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

The LCM of 402,661,406,204 is 1834013244.

Find LCM of 402,661,406,204 with Prime Factorization

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

2 x 3 x 67 x 661 x 203 x 34 = 1834013244

Therefore, the lowest common multiple of 402,661,406,204 is 1834013244.

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 661 x 406 x 204 = 22008158928

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

661 : 1, 661

406 : 1, 2, 7, 14, 29, 58, 203, 406

204 : 1, 2, 3, 4, 6, 12, 17, 34, 51, 68, 102, 204

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 402,661,406,204, is 1.

Now, the common factors can be found like this.

402:2x 3x 67

661:661

406:2x 7x 29

204:2x 2x 3x 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 3 = 12

Therefore, the value for common factors is 12.

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 = 22008158928/(1x12)

LCM = 22008158928/12

LCM = 1834013244

Thus, we can understand that the LCM of 402,661,406,204 is 1834013244.
