Find LCM of 968,387,978,405,105 with Prime Factorization
| 2 | 968, 387, 978, 405, 105 |
| 3 | 484, 387, 489, 405, 105 |
| 3 | 484, 129, 163, 135, 35 |
| 5 | 484, 43, 163, 45, 35 |
| 484, 43, 163, 9, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 484 x 43 x 163 x 9 x 7 = 19234658520
Therefore, the lowest common multiple of 968,387,978,405,105 is 19234658520.
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.
968 x 387 x 978 x 405 x 105 = 15580073401200
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.
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
387 : 1, 3, 9, 43, 129, 387
978 : 1, 2, 3, 6, 163, 326, 489, 978
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
105 : 1, 3, 5, 7, 15, 21, 35, 105
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 968,387,978,405,105, is 1.
Now, the common factors can be found like this.
968:2x 2x 2x 11x 11
387:3x 3x 43
978:2x 3x 163
405:3x 3x 3x 3x 5
105:3x 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 3x 5 = 810
Therefore, the value for common factors is 810.
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 = 15580073401200/(1x810)
LCM = 15580073401200/810
LCM = 19234658520
Thus, we can understand that the LCM of 968,387,978,405,105 is 19234658520.
