Find LCM of 660,979,181,447,808 with Prime Factorization
| 2 | 660, 979, 181, 447, 808 |
| 2 | 330, 979, 181, 447, 404 |
| 3 | 165, 979, 181, 447, 202 |
| 11 | 55, 979, 181, 149, 202 |
| 5, 89, 181, 149, 202 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 5 x 89 x 181 x 149 x 202 = 320000130120
Therefore, the lowest common multiple of 660,979,181,447,808 is 320000130120.
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.
660 x 979 x 181 x 447 x 808 = 42240017175840
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.
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
979 : 1, 11, 89, 979
181 : 1, 181
447 : 1, 3, 149, 447
808 : 1, 2, 4, 8, 101, 202, 404, 808
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,979,181,447,808, is 1.
Now, the common factors can be found like this.
660:2x 2x 3x 5x 11
979:11x 89
181:181
447:3x 149
808:2x 2x 2x 101
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 11 = 132
Therefore, the value for common factors is 132.
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 = 42240017175840/(1x132)
LCM = 42240017175840/132
LCM = 320000130120
Thus, we can understand that the LCM of 660,979,181,447,808 is 320000130120.
