Given numbers are 808,515,458,812
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 808,515,458,812 is 19344170440.
Find LCM of 808,515,458,812 with Prime Factorization
| 2 | 808, 515, 458, 812 |
| 2 | 404, 515, 229, 406 |
| 202, 515, 229, 203 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 202 x 515 x 229 x 203 = 19344170440
Therefore, the lowest common multiple of 808,515,458,812 is 19344170440.
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 515 x 458 x 812 = 154753363520
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
515 : 1, 5, 103, 515
458 : 1, 2, 229, 458
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 808,515,458,812, is 1.
Now, the common factors can be found like this.
808:2x 2x 2x 101
515:5x 103
458:2x 229
812:2x 2x 7x 29
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 2 = 8
Therefore, the value for common factors is 8.
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 = 154753363520/(1x8)
LCM = 154753363520/8
LCM = 19344170440
Thus, we can understand that the LCM of 808,515,458,812 is 19344170440.
