Given numbers are 395,515,724,821

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

The LCM of 395,515,724,821 is 24183326740.

Find LCM of 395,515,724,821 with Prime Factorization

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

5 x 79 x 103 x 724 x 821 = 24183326740

Therefore, the lowest common multiple of 395,515,724,821 is 24183326740.

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.

395 x 515 x 724 x 821 = 120916633700

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.

395 : 1, 5, 79, 395

515 : 1, 5, 103, 515

724 : 1, 2, 4, 181, 362, 724

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 395,515,724,821, is 1.

Now, the common factors can be found like this.

395:5x 79

515:5x 103

724:2x 2x 181

821:821

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 = 120916633700/(1x5)

LCM = 120916633700/5

LCM = 24183326740

Thus, we can understand that the LCM of 395,515,724,821 is 24183326740.
