Given numbers are 861,650,257,445

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

The LCM of 861,650,257,445 is 12800874450.

Find LCM of 861,650,257,445 with Prime Factorization

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

5 x 861 x 130 x 257 x 89 = 12800874450

Therefore, the lowest common multiple of 861,650,257,445 is 12800874450.

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.

861 x 650 x 257 x 445 = 64004372250

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.

861 : 1, 3, 7, 21, 41, 123, 287, 861

650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650

257 : 1, 257

445 : 1, 5, 89, 445

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,650,257,445, is 1.

Now, the common factors can be found like this.

861:3x 7x 41

650:2x 5x 5x 13

257:257

445:5x 89

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

5 = 5

Therefore, the value for common factors is 5.

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 = 64004372250/(1x5)

LCM = 64004372250/5

LCM = 12800874450

Thus, we can understand that the LCM of 861,650,257,445 is 12800874450.
