Given numbers are 808,418,247,871
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 808,418,247,871 is 147087512.
Find LCM of 808,418,247,871 with Prime Factorization
| 2 | 808, 418, 247, 871 |
| 13 | 404, 209, 247, 871 |
| 19 | 404, 209, 19, 67 |
| 404, 11, 1, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 19 x 404 x 11 x 1 x 67 = 147087512
Therefore, the lowest common multiple of 808,418,247,871 is 147087512.
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 418 x 247 x 871 = 72661230928
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
418 : 1, 2, 11, 19, 22, 38, 209, 418
247 : 1, 13, 19, 247
871 : 1, 13, 67, 871
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 808,418,247,871, is 1.
Now, the common factors can be found like this.
808:2x 2x 2x 101
418:2x 11x 19
247:13x 19
871:13x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 19 = 494
Therefore, the value for common factors is 494.
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 = 72661230928/(1x494)
LCM = 72661230928/494
LCM = 147087512
Thus, we can understand that the LCM of 808,418,247,871 is 147087512.
