Given numbers are 863,920,516,247

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

The LCM of 863,920,516,247 is 25297947480.

Find LCM of 863,920,516,247 with Prime Factorization

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

2 x 2 x 863 x 230 x 129 x 247 = 25297947480

Therefore, the lowest common multiple of 863,920,516,247 is 25297947480.

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.

863 x 920 x 516 x 247 = 101191789920

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.

863 : 1, 863

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516

247 : 1, 13, 19, 247

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 863,920,516,247, is 1.

Now, the common factors can be found like this.

863:863

920:2x 2x 2x 5x 23

516:2x 2x 3x 43

247:13x 19

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 = 101191789920/(1x4)

LCM = 101191789920/4

LCM = 25297947480

Thus, we can understand that the LCM of 863,920,516,247 is 25297947480.
