The LCM of 615,328,923,399 is 603974280.

Find LCM of 615,328,923,399 with Prime Factorization


3 615, 328, 923, 399
41 205, 328, 923, 133
5, 8, 923, 133

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

3 x 41 x 5 x 8 x 923 x 133 = 603974280

Therefore, the lowest common multiple of 615,328,923,399 is 603974280.

LCM Formula to Find Lowest Common Multiple of 615,328,923,399

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.

615 x 328 x 923 x 399 = 74288836440

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.

615 : 1, 3, 5, 15, 41, 123, 205, 615

328 : 1, 2, 4, 8, 41, 82, 164, 328

923 : 1, 13, 71, 923

399 : 1, 3, 7, 19, 21, 57, 133, 399

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 615,328,923,399, is 1.

Now, the common factors can be found like this.

615:3x 5x 41

328:2x 2x 2x 41

923:13x 71

399:3x 7x 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 41 = 123

Therefore, the value for common factors is 123.

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 = 74288836440/(1x123)

LCM = 74288836440/123

LCM = 603974280

Thus, we can understand that the LCM of 615,328,923,399 is 603974280.
