Given numbers are 818,391,520

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

The LCM of 818,391,520 is 83157880.

Find LCM of 818,391,520 with Prime Factorization

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

2 x 409 x 391 x 260 = 83157880

Therefore, the lowest common multiple of 818,391,520 is 83157880.

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.

818 x 391 x 520 = 166315760

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.

818 : 1, 2, 409, 818

391 : 1, 17, 23, 391

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 818,391,520, is 1.

Now, the common factors can be found like this.

818:2x 409

391:17x 23

520:2x 2x 2x 5x 13

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 = 166315760/(1x2)

LCM = 166315760/2

LCM = 83157880

Thus, we can understand that the LCM of 818,391,520 is 83157880.
