Given numbers are 686,442,317,896,305

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

The LCM of 686,442,317,896,305 is 938113671040.

Find LCM of 686,442,317,896,305 with Prime Factorization

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

2 x 7 x 49 x 221 x 317 x 64 x 305 = 938113671040

Therefore, the lowest common multiple of 686,442,317,896,305 is 938113671040.

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.

686 x 442 x 317 x 896 x 305 = 26267182789120

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.

686 : 1, 2, 7, 14, 49, 98, 343, 686

442 : 1, 2, 13, 17, 26, 34, 221, 442

317 : 1, 317

896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896

305 : 1, 5, 61, 305

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,442,317,896,305, is 1.

Now, the common factors can be found like this.

686:2x 7x 7x 7

442:2x 13x 17

317:317

896:2x 2x 2x 2x 2x 2x 2x 7

305:5x 61

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

2x 2x 7 = 28

Therefore, the value for common factors is 28.

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 = 26267182789120/(1x28)

LCM = 26267182789120/28

LCM = 938113671040

Thus, we can understand that the LCM of 686,442,317,896,305 is 938113671040.
