Given numbers are 361,643,818,840

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

The LCM of 361,643,818,840 is 79748177880.

Find LCM of 361,643,818,840 with Prime Factorization

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

2 x 361 x 643 x 409 x 420 = 79748177880

Therefore, the lowest common multiple of 361,643,818,840 is 79748177880.

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.

361 x 643 x 818 x 840 = 159496355760

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.

361 : 1, 19, 361

643 : 1, 643

818 : 1, 2, 409, 818

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 361,643,818,840, is 1.

Now, the common factors can be found like this.

361:19x 19

643:643

818:2x 409

840:2x 2x 2x 3x 5x 7

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

2 = 2

Therefore, the value for common factors is 2.

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 = 159496355760/(1x2)

LCM = 159496355760/2

LCM = 79748177880

Thus, we can understand that the LCM of 361,643,818,840 is 79748177880.
