Given numbers are 579,412,721,836
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 579,412,721,836 is 348995724.
Find LCM of 579,412,721,836 with Prime Factorization
| 2 | 579, 412, 721, 836 |
| 2 | 579, 206, 721, 418 |
| 103 | 579, 103, 721, 209 |
| 579, 1, 7, 209 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 103 x 579 x 1 x 7 x 209 = 348995724
Therefore, the lowest common multiple of 579,412,721,836 is 348995724.
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.
579 x 412 x 721 x 836 = 143786238288
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.
579 : 1, 3, 193, 579
412 : 1, 2, 4, 103, 206, 412
721 : 1, 7, 103, 721
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 579,412,721,836, is 1.
Now, the common factors can be found like this.
579:3x 193
412:2x 2x 103
721:7x 103
836:2x 2x 11x 19
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 103 = 412
Therefore, the value for common factors is 412.
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 = 143786238288/(1x412)
LCM = 143786238288/412
LCM = 348995724
Thus, we can understand that the LCM of 579,412,721,836 is 348995724.
