Calculate the LCM of 859,520,789,815

Given numbers are 859,520,789,815

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

The LCM of 859,520,789,815 is 57446174760.

Find LCM of 859,520,789,815 with Prime Factorization


5 859, 520, 789, 815
859, 104, 789, 163

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

5 x 859 x 104 x 789 x 163 = 57446174760

Therefore, the lowest common multiple of 859,520,789,815 is 57446174760.

LCM Formula to Find Lowest Common Multiple of 859,520,789,815

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.

859 x 520 x 789 x 815 = 287230873800

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.

859 : 1, 859

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

789 : 1, 3, 263, 789

815 : 1, 5, 163, 815

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 859,520,789,815, is 1.

Now, the common factors can be found like this.

859:859

520:2x 2x 2x 5x 13

789:3x 263

815:5x 163

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

5 = 5

Therefore, the value for common factors is 5.

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 = 287230873800/(1x5)

LCM = 287230873800/5

LCM = 57446174760

Thus, we can understand that the LCM of 859,520,789,815 is 57446174760.
