Find LCM of 813,608,460,160 with Prime Factorization
| 2 | 813, 608, 460, 160 |
| 2 | 813, 304, 230, 80 |
| 2 | 813, 152, 115, 40 |
| 2 | 813, 76, 115, 20 |
| 2 | 813, 38, 115, 10 |
| 5 | 813, 19, 115, 5 |
| 813, 19, 23, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 5 x 813 x 19 x 23 x 1 = 56844960
Therefore, the lowest common multiple of 813,608,460,160 is 56844960.
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.
813 x 608 x 460 x 160 = 36380774400
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.
813 : 1, 3, 271, 813
608 : 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304, 608
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,608,460,160, is 1.
Now, the common factors can be found like this.
813:3x 271
608:2x 2x 2x 2x 2x 19
460:2x 2x 5x 23
160:2x 2x 2x 2x 2x 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 2x 2x 2x 2x 5 = 640
Therefore, the value for common factors is 640.
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 = 36380774400/(1x640)
LCM = 36380774400/640
LCM = 56844960
Thus, we can understand that the LCM of 813,608,460,160 is 56844960.
