Given numbers are 865,316,290,418,257

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

The LCM of 865,316,290,418,257 is 425775431180.

Find LCM of 865,316,290,418,257 with Prime Factorization

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

2 x 5 x 173 x 158 x 29 x 209 x 257 = 425775431180

Therefore, the lowest common multiple of 865,316,290,418,257 is 425775431180.

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.

865 x 316 x 290 x 418 x 257 = 8515508623600

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.

865 : 1, 5, 173, 865

316 : 1, 2, 4, 79, 158, 316

290 : 1, 2, 5, 10, 29, 58, 145, 290

418 : 1, 2, 11, 19, 22, 38, 209, 418

257 : 1, 257

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 865,316,290,418,257, is 1.

Now, the common factors can be found like this.

865:5x 173

316:2x 2x 79

290:2x 5x 29

418:2x 11x 19

257:257

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 5 = 20

Therefore, the value for common factors is 20.

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 = 8515508623600/(1x20)

LCM = 8515508623600/20

LCM = 425775431180

Thus, we can understand that the LCM of 865,316,290,418,257 is 425775431180.
