Given numbers are 285,772,781,869

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

The LCM of 285,772,781,869 is 13575013980.

Find LCM of 285,772,781,869 with Prime Factorization

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

11 x 285 x 772 x 71 x 79 = 13575013980

Therefore, the lowest common multiple of 285,772,781,869 is 13575013980.

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.

285 x 772 x 781 x 869 = 149325153780

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.

285 : 1, 3, 5, 15, 19, 57, 95, 285

772 : 1, 2, 4, 193, 386, 772

781 : 1, 11, 71, 781

869 : 1, 11, 79, 869

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 285,772,781,869, is 1.

Now, the common factors can be found like this.

285:3x 5x 19

772:2x 2x 193

781:11x 71

869:11x 79

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

11 = 11

Therefore, the value for common factors is 11.

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 = 149325153780/(1x11)

LCM = 149325153780/11

LCM = 13575013980

Thus, we can understand that the LCM of 285,772,781,869 is 13575013980.
