Given numbers are 515,705,424,515

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

The LCM of 515,705,424,515 is 30788760.

Find LCM of 515,705,424,515 with Prime Factorization

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

5 x 103 x 1 x 141 x 424 x 1 = 30788760

Therefore, the lowest common multiple of 515,705,424,515 is 30788760.

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 705 x 424 x 515 = 79281057000

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

705 : 1, 3, 5, 15, 47, 141, 235, 705

424 : 1, 2, 4, 8, 53, 106, 212, 424

515 : 1, 5, 103, 515

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 515,705,424,515, is 1.

Now, the common factors can be found like this.

515:5x 103

705:3x 5x 47

424:2x 2x 2x 53

515:5x 103

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

5x 5x 103 = 2575

Therefore, the value for common factors is 2575.

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 = 79281057000/(1x2575)

LCM = 79281057000/2575

LCM = 30788760

Thus, we can understand that the LCM of 515,705,424,515 is 30788760.
