Calculate the LCM of 915,643,560,958

Given numbers are 915,643,560,958

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

The LCM of 915,643,560,958 is 31563532560.

Find LCM of 915,643,560,958 with Prime Factorization


2 915, 643, 560, 958
5 915, 643, 280, 479
183, 643, 56, 479

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

2 x 5 x 183 x 643 x 56 x 479 = 31563532560

Therefore, the lowest common multiple of 915,643,560,958 is 31563532560.

LCM Formula to Find Lowest Common Multiple of 915,643,560,958

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.

915 x 643 x 560 x 958 = 315635325600

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.

915 : 1, 3, 5, 15, 61, 183, 305, 915

643 : 1, 643

560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560

958 : 1, 2, 479, 958

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 915,643,560,958, is 1.

Now, the common factors can be found like this.

915:3x 5x 61

643:643

560:2x 2x 2x 2x 5x 7

958:2x 479

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 = 315635325600/(1x10)

LCM = 315635325600/10

LCM = 31563532560

Thus, we can understand that the LCM of 915,643,560,958 is 31563532560.
