Given numbers are 327,836,645,660
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 327,836,645,660 is 58774980.
Find LCM of 327,836,645,660 with Prime Factorization
| 2 | 327, 836, 645, 660 |
| 2 | 327, 418, 645, 330 |
| 3 | 327, 209, 645, 165 |
| 5 | 109, 209, 215, 55 |
| 11 | 109, 209, 43, 11 |
| 109, 19, 43, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 11 x 109 x 19 x 43 x 1 = 58774980
Therefore, the lowest common multiple of 327,836,645,660 is 58774980.
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.
327 x 836 x 645 x 660 = 116374460400
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.
327 : 1, 3, 109, 327
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
645 : 1, 3, 5, 15, 43, 129, 215, 645
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 327,836,645,660, is 1.
Now, the common factors can be found like this.
327:3x 109
836:2x 2x 11x 19
645:3x 5x 43
660:2x 2x 3x 5x 11
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 3x 3x 5x 11 = 1980
Therefore, the value for common factors is 1980.
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 = 116374460400/(1x1980)
LCM = 116374460400/1980
LCM = 58774980
Thus, we can understand that the LCM of 327,836,645,660 is 58774980.
