Find LCM of 328,836,798,919,405 with Prime Factorization
| 2 | 328, 836, 798, 919, 405 |
| 2 | 164, 418, 399, 919, 405 |
| 3 | 82, 209, 399, 919, 405 |
| 19 | 82, 209, 133, 919, 135 |
| 82, 11, 7, 919, 135 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 19 x 82 x 11 x 7 x 919 x 135 = 178602981480
Therefore, the lowest common multiple of 328,836,798,919,405 is 178602981480.
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.
328 x 836 x 798 x 919 x 405 = 81442959554880
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.
328 : 1, 2, 4, 8, 41, 82, 164, 328
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
919 : 1, 919
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 328,836,798,919,405, is 1.
Now, the common factors can be found like this.
328:2x 2x 2x 41
836:2x 2x 11x 19
798:2x 3x 7x 19
919:919
405:3x 3x 3x 3x 5
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 3x 19 = 456
Therefore, the value for common factors is 456.
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 = 81442959554880/(1x456)
LCM = 81442959554880/456
LCM = 178602981480
Thus, we can understand that the LCM of 328,836,798,919,405 is 178602981480.
