Calculate the LCM of 520,300,815,865

Given numbers are 520,300,815,865

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

The LCM of 520,300,815,865 is 219952200.

Find LCM of 520,300,815,865 with Prime Factorization


2 520, 300, 815, 865
2 260, 150, 815, 865
5 130, 75, 815, 865
26, 15, 163, 173

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

2 x 2 x 5 x 26 x 15 x 163 x 173 = 219952200

Therefore, the lowest common multiple of 520,300,815,865 is 219952200.

LCM Formula to Find Lowest Common Multiple of 520,300,815,865

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.

520 x 300 x 815 x 865 = 109976100000

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.

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

300 : 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 25, 30, 50, 60, 75, 100, 150, 300

815 : 1, 5, 163, 815

865 : 1, 5, 173, 865

5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,300,815,865, is 5.

Now, the common factors can be found like this.

520:2x 2x 2x 5x 13

300:2x 2x 3x 5x 5

815:5x 163

865:5x 173

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 5x 5 = 100

Therefore, the value for common factors is 100.

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 = 109976100000/(5x100)

LCM = 109976100000/500

LCM = 219952200

Thus, we can understand that the LCM of 520,300,815,865 is 219952200.
