Given numbers are 247,811,399,985

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

The LCM of 247,811,399,985 is 4143557145.

Find LCM of 247,811,399,985 with Prime Factorization

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

19 x 13 x 811 x 21 x 985 = 4143557145

Therefore, the lowest common multiple of 247,811,399,985 is 4143557145.

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 811 x 399 x 985 = 78727585755

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

811 : 1, 811

399 : 1, 3, 7, 19, 21, 57, 133, 399

985 : 1, 5, 197, 985

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,811,399,985, is 1.

Now, the common factors can be found like this.

247:13x 19

811:811

399:3x 7x 19

985:5x 197

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

19 = 19

Therefore, the value for common factors is 19.

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 = 78727585755/(1x19)

LCM = 78727585755/19

LCM = 4143557145

Thus, we can understand that the LCM of 247,811,399,985 is 4143557145.
