Given numbers are 385,642,445,865

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

The LCM of 385,642,445,865 is 3805676490.

Find LCM of 385,642,445,865 with Prime Factorization

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

5 x 77 x 642 x 89 x 173 = 3805676490

Therefore, the lowest common multiple of 385,642,445,865 is 3805676490.

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.

385 x 642 x 445 x 865 = 95141912250

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.

385 : 1, 5, 7, 11, 35, 55, 77, 385

642 : 1, 2, 3, 6, 107, 214, 321, 642

445 : 1, 5, 89, 445

865 : 1, 5, 173, 865

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 385,642,445,865, is 1.

Now, the common factors can be found like this.

385:5x 7x 11

642:2x 3x 107

445:5x 89

865:5x 173

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 95141912250/(1x25)

LCM = 95141912250/25

LCM = 3805676490

Thus, we can understand that the LCM of 385,642,445,865 is 3805676490.
