Given numbers are 816,872,783,904
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 816,872,783,904 is 2623225392.
Find LCM of 816,872,783,904 with Prime Factorization
| 2 | 816, 872, 783, 904 |
| 2 | 408, 436, 783, 452 |
| 2 | 204, 218, 783, 226 |
| 3 | 102, 109, 783, 113 |
| 34, 109, 261, 113 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 34 x 109 x 261 x 113 = 2623225392
Therefore, the lowest common multiple of 816,872,783,904 is 2623225392.
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 872 x 783 x 904 = 503659275264
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
872 : 1, 2, 4, 8, 109, 218, 436, 872
783 : 1, 3, 9, 27, 29, 87, 261, 783
904 : 1, 2, 4, 8, 113, 226, 452, 904
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,872,783,904, is 1.
Now, the common factors can be found like this.
816:2x 2x 2x 2x 3x 17
872:2x 2x 2x 109
783:3x 3x 3x 29
904:2x 2x 2x 113
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 3 = 192
Therefore, the value for common factors is 192.
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 = 503659275264/(1x192)
LCM = 503659275264/192
LCM = 2623225392
Thus, we can understand that the LCM of 816,872,783,904 is 2623225392.
