Given numbers are 517,520,538,395

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

The LCM of 517,520,538,395 is 5713118840.

Find LCM of 517,520,538,395 with Prime Factorization

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

2 x 5 x 517 x 52 x 269 x 79 = 5713118840

Therefore, the lowest common multiple of 517,520,538,395 is 5713118840.

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.

517 x 520 x 538 x 395 = 57131188400

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.

517 : 1, 11, 47, 517

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

538 : 1, 2, 269, 538

395 : 1, 5, 79, 395

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 517,520,538,395, is 1.

Now, the common factors can be found like this.

517:11x 47

520:2x 2x 2x 5x 13

538:2x 269

395:5x 79

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 57131188400/(1x10)

LCM = 57131188400/10

LCM = 5713118840

Thus, we can understand that the LCM of 517,520,538,395 is 5713118840.
