Given numbers are 856,340,349,287

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

The LCM of 856,340,349,287 is 7287859880.

Find LCM of 856,340,349,287 with Prime Factorization

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

2 x 2 x 214 x 85 x 349 x 287 = 7287859880

Therefore, the lowest common multiple of 856,340,349,287 is 7287859880.

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.

856 x 340 x 349 x 287 = 29151439520

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.

856 : 1, 2, 4, 8, 107, 214, 428, 856

340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340

349 : 1, 349

287 : 1, 7, 41, 287

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 856,340,349,287, is 1.

Now, the common factors can be found like this.

856:2x 2x 2x 107

340:2x 2x 5x 17

349:349

287:7x 41

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 = 29151439520/(1x4)

LCM = 29151439520/4

LCM = 7287859880

Thus, we can understand that the LCM of 856,340,349,287 is 7287859880.
