Given numbers are 808,628,940,520
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 808,628,940,520 is 387545080.
Find LCM of 808,628,940,520 with Prime Factorization
| 2 | 808, 628, 940, 520 |
| 2 | 404, 314, 470, 260 |
| 2 | 202, 157, 235, 130 |
| 5 | 101, 157, 235, 65 |
| 101, 157, 47, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 101 x 157 x 47 x 13 = 387545080
Therefore, the lowest common multiple of 808,628,940,520 is 387545080.
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.
808 x 628 x 940 x 520 = 248028851200
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.
808 : 1, 2, 4, 8, 101, 202, 404, 808
628 : 1, 2, 4, 157, 314, 628
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 808,628,940,520, is 4.
Now, the common factors can be found like this.
808:2x 2x 2x 101
628:2x 2x 157
940:2x 2x 5x 47
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.
2x 2x 2x 2x 2x 5 = 160
Therefore, the value for common factors is 160.
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 = 248028851200/(4x160)
LCM = 248028851200/640
LCM = 387545080
Thus, we can understand that the LCM of 808,628,940,520 is 387545080.
