Given numbers are 643,804,286,887

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

The LCM of 643,804,286,887 is 65573245452.

Find LCM of 643,804,286,887 with Prime Factorization

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

2 x 643 x 402 x 143 x 887 = 65573245452

Therefore, the lowest common multiple of 643,804,286,887 is 65573245452.

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.

643 x 804 x 286 x 887 = 131146490904

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.

643 : 1, 643

804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804

286 : 1, 2, 11, 13, 22, 26, 143, 286

887 : 1, 887

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,804,286,887, is 1.

Now, the common factors can be found like this.

643:643

804:2x 2x 3x 67

286:2x 11x 13

887:887

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 = 131146490904/(1x2)

LCM = 131146490904/2

LCM = 65573245452

Thus, we can understand that the LCM of 643,804,286,887 is 65573245452.
