Calculate the LCM of 515,239,345,855

Given numbers are 515,239,345,855

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

The LCM of 515,239,345,855 is 484093305.

Find LCM of 515,239,345,855 with Prime Factorization


3 515, 239, 345, 855
5 515, 239, 115, 285
103, 239, 23, 57

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

3 x 5 x 103 x 239 x 23 x 57 = 484093305

Therefore, the lowest common multiple of 515,239,345,855 is 484093305.

LCM Formula to Find Lowest Common Multiple of 515,239,345,855

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.

515 x 239 x 345 x 855 = 36306997875

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.

515 : 1, 5, 103, 515

239 : 1, 239

345 : 1, 3, 5, 15, 23, 69, 115, 345

855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 515,239,345,855, is 1.

Now, the common factors can be found like this.

515:5x 103

239:239

345:3x 5x 23

855:3x 3x 5x 19

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

3x 5x 5 = 75

Therefore, the value for common factors is 75.

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 = 36306997875/(1x75)

LCM = 36306997875/75

LCM = 484093305

Thus, we can understand that the LCM of 515,239,345,855 is 484093305.
