Given numbers are 390,515,660,495

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

The LCM of 390,515,660,495 is 2651220.

Find LCM of 390,515,660,495 with Prime Factorization

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

2 x 3 x 5 x 11 x 13 x 103 x 2 x 3 = 2651220

Therefore, the lowest common multiple of 390,515,660,495 is 2651220.

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.

390 x 515 x 660 x 495 = 65617695000

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.

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

515 : 1, 5, 103, 515

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495

5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 390,515,660,495, is 5.

Now, the common factors can be found like this.

390:2x 3x 5x 13

515:5x 103

660:2x 2x 3x 5x 11

495:3x 3x 5x 11

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

2x 3x 3x 5x 5x 11 = 4950

Therefore, the value for common factors is 4950.

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 = 65617695000/(5x4950)

LCM = 65617695000/24750

LCM = 2651220

Thus, we can understand that the LCM of 390,515,660,495 is 2651220.
