Given numbers are 390,248,515,326

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

The LCM of 390,248,515,326 is 811916040.

Find LCM of 390,248,515,326 with Prime Factorization

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

2 x 5 x 39 x 124 x 103 x 163 = 811916040

Therefore, the lowest common multiple of 390,248,515,326 is 811916040.

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 248 x 515 x 326 = 16238320800

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

248 : 1, 2, 4, 8, 31, 62, 124, 248

515 : 1, 5, 103, 515

326 : 1, 2, 163, 326

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 390,248,515,326, is 1.

Now, the common factors can be found like this.

390:2x 3x 5x 13

248:2x 2x 2x 31

515:5x 103

326:2x 163

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

2x 2x 5 = 20

Therefore, the value for common factors is 20.

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 = 16238320800/(1x20)

LCM = 16238320800/20

LCM = 811916040

Thus, we can understand that the LCM of 390,248,515,326 is 811916040.
