Find LCM of 816,540,369,398,917 with Prime Factorization
| 2 | 816, 540, 369, 398, 917 |
| 2 | 408, 270, 369, 199, 917 |
| 3 | 204, 135, 369, 199, 917 |
| 3 | 68, 45, 123, 199, 917 |
| 68, 15, 41, 199, 917 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 68 x 15 x 41 x 199 x 917 = 274731806160
Therefore, the lowest common multiple of 816,540,369,398,917 is 274731806160.
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.
816 x 540 x 369 x 398 x 917 = 59342070130560
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.
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
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
369 : 1, 3, 9, 41, 123, 369
398 : 1, 2, 199, 398
917 : 1, 7, 131, 917
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,540,369,398,917, is 1.
Now, the common factors can be found like this.
816:2x 2x 2x 2x 3x 17
540:2x 2x 3x 3x 3x 5
369:3x 3x 41
398:2x 199
917:7x 131
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 3x 3 = 216
Therefore, the value for common factors is 216.
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 = 59342070130560/(1x216)
LCM = 59342070130560/216
LCM = 274731806160
Thus, we can understand that the LCM of 816,540,369,398,917 is 274731806160.
