Given numbers are 247,953,703,855

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

The LCM of 247,953,703,855 is 391926015.

Find LCM of 247,953,703,855 with Prime Factorization

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

19 x 13 x 953 x 37 x 45 = 391926015

Therefore, the lowest common multiple of 247,953,703,855 is 391926015.

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.

247 x 953 x 703 x 855 = 141485291415

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.

247 : 1, 13, 19, 247

953 : 1, 953

703 : 1, 19, 37, 703

855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,953,703,855, is 1.

Now, the common factors can be found like this.

247:13x 19

953:953

703:19x 37

855:3x 3x 5x 19

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

19x 19 = 361

Therefore, the value for common factors is 361.

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 = 141485291415/(1x361)

LCM = 141485291415/361

LCM = 391926015

Thus, we can understand that the LCM of 247,953,703,855 is 391926015.
