The LCM of 988,609,918,315 is 460294380.
Find LCM of 988,609,918,315 with Prime Factorization
| 2 | 988, 609, 918, 315 |
| 3 | 494, 609, 459, 315 |
| 3 | 494, 203, 153, 105 |
| 7 | 494, 203, 51, 35 |
| 494, 29, 51, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 494 x 29 x 51 x 5 = 460294380
Therefore, the lowest common multiple of 988,609,918,315 is 460294380.
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.
988 x 609 x 918 x 315 = 173991275640
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.
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
609 : 1, 3, 7, 21, 29, 87, 203, 609
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 988,609,918,315, is 1.
Now, the common factors can be found like this.
988:2x 2x 13x 19
609:3x 7x 29
918:2x 3x 3x 3x 17
315:3x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 7 = 378
Therefore, the value for common factors is 378.
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 = 173991275640/(1x378)
LCM = 173991275640/378
LCM = 460294380
Thus, we can understand that the LCM of 988,609,918,315 is 460294380.
