The LCM of 918,815,578,163 is 12718890.
Find LCM of 918,815,578,163 with Prime Factorization
| 2 | 918, 815, 578, 163 |
| 17 | 459, 815, 289, 163 |
| 163 | 27, 815, 17, 163 |
| 27, 5, 17, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 163 x 27 x 5 x 17 x 1 = 12718890
Therefore, the lowest common multiple of 918,815,578,163 is 12718890.
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.
918 x 815 x 578 x 163 = 70488088380
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.
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
815 : 1, 5, 163, 815
578 : 1, 2, 17, 34, 289, 578
163 : 1, 163
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 918,815,578,163, is 1.
Now, the common factors can be found like this.
918:2x 3x 3x 3x 17
815:5x 163
578:2x 17x 17
163:163
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 17x 163 = 5542
Therefore, the value for common factors is 5542.
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 = 70488088380/(1x5542)
LCM = 70488088380/5542
LCM = 12718890
Thus, we can understand that the LCM of 918,815,578,163 is 12718890.
