Given numbers are 919,916,209,540

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

The LCM of 919,916,209,540 is 23751499860.

Find LCM of 919,916,209,540 with Prime Factorization

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

2 x 2 x 919 x 229 x 209 x 135 = 23751499860

Therefore, the lowest common multiple of 919,916,209,540 is 23751499860.

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.

919 x 916 x 209 x 540 = 95005999440

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.

919 : 1, 919

916 : 1, 2, 4, 229, 458, 916

209 : 1, 11, 19, 209

540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 919,916,209,540, is 1.

Now, the common factors can be found like this.

919:919

916:2x 2x 229

209:11x 19

540:2x 2x 3x 3x 3x 5

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 = 95005999440/(1x4)

LCM = 95005999440/4

LCM = 23751499860

Thus, we can understand that the LCM of 919,916,209,540 is 23751499860.
