Find LCM of 816,513,195,783,771 with Prime Factorization
| 3 | 816, 513, 195, 783, 771 |
| 3 | 272, 171, 65, 261, 257 |
| 3 | 272, 57, 65, 87, 257 |
| 272, 19, 65, 29, 257 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 272 x 19 x 65 x 29 x 257 = 67597517520
Therefore, the lowest common multiple of 816,513,195,783,771 is 67597517520.
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 513 x 195 x 783 x 771 = 49278590272080
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
513 : 1, 3, 9, 19, 27, 57, 171, 513
195 : 1, 3, 5, 13, 15, 39, 65, 195
783 : 1, 3, 9, 27, 29, 87, 261, 783
771 : 1, 3, 257, 771
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,513,195,783,771, is 3.
Now, the common factors can be found like this.
816:2x 2x 2x 2x 3x 17
513:3x 3x 3x 19
195:3x 5x 13
783:3x 3x 3x 29
771:3x 257
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 3 = 243
Therefore, the value for common factors is 243.
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 = 49278590272080/(3x243)
LCM = 49278590272080/729
LCM = 67597517520
Thus, we can understand that the LCM of 816,513,195,783,771 is 67597517520.
