The LCM of 718,207,978,540,684 is 13808841660.
Find LCM of 718,207,978,540,684 with Prime Factorization
| 2 | 718, 207, 978, 540, 684 |
| 2 | 359, 207, 489, 270, 342 |
| 3 | 359, 207, 489, 135, 171 |
| 3 | 359, 69, 163, 45, 57 |
| 359, 23, 163, 15, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 359 x 23 x 163 x 15 x 19 = 13808841660
Therefore, the lowest common multiple of 718,207,978,540,684 is 13808841660.
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.
718 x 207 x 978 x 540 x 684 = 53688776374080
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.
718 : 1, 2, 359, 718
207 : 1, 3, 9, 23, 69, 207
978 : 1, 2, 3, 6, 163, 326, 489, 978
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 718,207,978,540,684, is 1.
Now, the common factors can be found like this.
718:2x 359
207:3x 3x 23
978:2x 3x 163
540:2x 2x 3x 3x 3x 5
684:2x 2x 3x 3x 19
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 3x 3x 3x 3x 3 = 3888
Therefore, the value for common factors is 3888.
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 = 53688776374080/(1x3888)
LCM = 53688776374080/3888
LCM = 13808841660
Thus, we can understand that the LCM of 718,207,978,540,684 is 13808841660.
