Given numbers are 402,805,706,218

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

The LCM of 402,805,706,218 is 12451541970.

Find LCM of 402,805,706,218 with Prime Factorization

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

2 x 201 x 805 x 353 x 109 = 12451541970

Therefore, the lowest common multiple of 402,805,706,218 is 12451541970.

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 805 x 706 x 218 = 49806167880

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

805 : 1, 5, 7, 23, 35, 115, 161, 805

706 : 1, 2, 353, 706

218 : 1, 2, 109, 218

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 402,805,706,218, is 1.

Now, the common factors can be found like this.

402:2x 3x 67

805:5x 7x 23

706:2x 353

218:2x 109

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 = 49806167880/(1x4)

LCM = 49806167880/4

LCM = 12451541970

Thus, we can understand that the LCM of 402,805,706,218 is 12451541970.
