Given numbers are 820,338,718,487

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

The LCM of 820,338,718,487 is 24228357140.

Find LCM of 820,338,718,487 with Prime Factorization

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

2 x 410 x 169 x 359 x 487 = 24228357140

Therefore, the lowest common multiple of 820,338,718,487 is 24228357140.

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.

820 x 338 x 718 x 487 = 96913428560

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.

820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820

338 : 1, 2, 13, 26, 169, 338

718 : 1, 2, 359, 718

487 : 1, 487

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 820,338,718,487, is 1.

Now, the common factors can be found like this.

820:2x 2x 5x 41

338:2x 13x 13

718:2x 359

487:487

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 96913428560/(1x4)

LCM = 96913428560/4

LCM = 24228357140

Thus, we can understand that the LCM of 820,338,718,487 is 24228357140.
