The LCM of 305,408,911,515,216 is 105089206680.
Find LCM of 305,408,911,515,216 with Prime Factorization
| 2 | 305, 408, 911, 515, 216 |
| 2 | 305, 204, 911, 515, 108 |
| 2 | 305, 102, 911, 515, 54 |
| 3 | 305, 51, 911, 515, 27 |
| 5 | 305, 17, 911, 515, 9 |
| 61, 17, 911, 103, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 61 x 17 x 911 x 103 x 9 = 105089206680
Therefore, the lowest common multiple of 305,408,911,515,216 is 105089206680.
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.
305 x 408 x 911 x 515 x 216 = 12610704801600
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.
305 : 1, 5, 61, 305
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
911 : 1, 911
515 : 1, 5, 103, 515
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 305,408,911,515,216, is 1.
Now, the common factors can be found like this.
305:5x 61
408:2x 2x 2x 3x 17
911:911
515:5x 103
216:2x 2x 2x 3x 3x 3
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 3x 5 = 120
Therefore, the value for common factors is 120.
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 = 12610704801600/(1x120)
LCM = 12610704801600/120
LCM = 105089206680
Thus, we can understand that the LCM of 305,408,911,515,216 is 105089206680.
