Given numbers are 306,878,620,389

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

The LCM of 306,878,620,389 is 16199337060.

Find LCM of 306,878,620,389 with Prime Factorization

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

2 x 153 x 439 x 310 x 389 = 16199337060

Therefore, the lowest common multiple of 306,878,620,389 is 16199337060.

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.

306 x 878 x 620 x 389 = 64797348240

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.

306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306

878 : 1, 2, 439, 878

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

389 : 1, 389

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 306,878,620,389, is 1.

Now, the common factors can be found like this.

306:2x 3x 3x 17

878:2x 439

620:2x 2x 5x 31

389:389

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 = 64797348240/(1x4)

LCM = 64797348240/4

LCM = 16199337060

Thus, we can understand that the LCM of 306,878,620,389 is 16199337060.
