Find LCM of 816,280,864,244,546 with Prime Factorization
| 2 | 816, 280, 864, 244, 546 |
| 2 | 408, 140, 432, 122, 273 |
| 2 | 204, 70, 216, 61, 273 |
| 2 | 102, 35, 108, 61, 273 |
| 3 | 51, 35, 54, 61, 273 |
| 7 | 17, 35, 18, 61, 91 |
| 17, 5, 18, 61, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 7 x 17 x 5 x 18 x 61 x 13 = 407665440
Therefore, the lowest common multiple of 816,280,864,244,546 is 407665440.
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 280 x 864 x 244 x 546 = 26299312865280
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
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864
244 : 1, 2, 4, 61, 122, 244
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,280,864,244,546, is 2.
Now, the common factors can be found like this.
816:2x 2x 2x 2x 3x 17
280:2x 2x 2x 5x 7
864:2x 2x 2x 2x 2x 3x 3x 3
244:2x 2x 61
546:2x 3x 7x 13
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 2x 2x 2x 2x 2x 3x 3x 7 = 32256
Therefore, the value for common factors is 32256.
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 = 26299312865280/(2x32256)
LCM = 26299312865280/64512
LCM = 407665440
Thus, we can understand that the LCM of 816,280,864,244,546 is 407665440.
