The LCM of 678,112,816,916 is 147809424.
Find LCM of 678,112,816,916 with Prime Factorization
| 2 | 678, 112, 816, 916 |
| 2 | 339, 56, 408, 458 |
| 2 | 339, 28, 204, 229 |
| 2 | 339, 14, 102, 229 |
| 3 | 339, 7, 51, 229 |
| 113, 7, 17, 229 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 113 x 7 x 17 x 229 = 147809424
Therefore, the lowest common multiple of 678,112,816,916 is 147809424.
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.
678 x 112 x 816 x 916 = 56758818816
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.
678 : 1, 2, 3, 6, 113, 226, 339, 678
112 : 1, 2, 4, 7, 8, 14, 16, 28, 56, 112
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
916 : 1, 2, 4, 229, 458, 916
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,112,816,916, is 2.
Now, the common factors can be found like this.
678:2x 3x 113
112:2x 2x 2x 2x 7
816:2x 2x 2x 2x 3x 17
916:2x 2x 229
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 = 56758818816/(2x192)
LCM = 56758818816/384
LCM = 147809424
Thus, we can understand that the LCM of 678,112,816,916 is 147809424.
