Given numbers are 247,451,451,809

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

The LCM of 247,451,451,809 is 90120173.

Find LCM of 247,451,451,809 with Prime Factorization

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

11 x 41 x 247 x 1 x 1 x 809 = 90120173

Therefore, the lowest common multiple of 247,451,451,809 is 90120173.

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 451 x 451 x 809 = 40644198023

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

451 : 1, 11, 41, 451

451 : 1, 11, 41, 451

809 : 1, 809

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,451,451,809, is 1.

Now, the common factors can be found like this.

247:13x 19

451:11x 41

451:11x 41

809:809

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

11x 41 = 451

Therefore, the value for common factors is 451.

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 = 40644198023/(1x451)

LCM = 40644198023/451

LCM = 90120173

Thus, we can understand that the LCM of 247,451,451,809 is 90120173.
