Calculate the LCM of 815,589,856,578

Given numbers are 815,589,856,578

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

The LCM of 815,589,856,578 is 118752978440.

Find LCM of 815,589,856,578 with Prime Factorization


2 815, 589, 856, 578
815, 589, 428, 289

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

2 x 815 x 589 x 428 x 289 = 118752978440

Therefore, the lowest common multiple of 815,589,856,578 is 118752978440.

LCM Formula to Find Lowest Common Multiple of 815,589,856,578

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.

815 x 589 x 856 x 578 = 237505956880

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.

815 : 1, 5, 163, 815

589 : 1, 19, 31, 589

856 : 1, 2, 4, 8, 107, 214, 428, 856

578 : 1, 2, 17, 34, 289, 578

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,589,856,578, is 1.

Now, the common factors can be found like this.

815:5x 163

589:19x 31

856:2x 2x 2x 107

578:2x 17x 17

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

2 = 2

Therefore, the value for common factors is 2.

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 = 237505956880/(1x2)

LCM = 237505956880/2

LCM = 118752978440

Thus, we can understand that the LCM of 815,589,856,578 is 118752978440.
