The LCM of 834,416,988,646 is 56031456.
Find LCM of 834,416,988,646 with Prime Factorization
| 2 | 834, 416, 988, 646 |
| 2 | 417, 208, 494, 323 |
| 13 | 417, 104, 247, 323 |
| 19 | 417, 8, 19, 323 |
| 417, 8, 1, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 19 x 417 x 8 x 1 x 17 = 56031456
Therefore, the lowest common multiple of 834,416,988,646 is 56031456.
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.
834 x 416 x 988 x 646 = 221436314112
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.
834 : 1, 2, 3, 6, 139, 278, 417, 834
416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
646 : 1, 2, 17, 19, 34, 38, 323, 646
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 834,416,988,646, is 2.
Now, the common factors can be found like this.
834:2x 3x 139
416:2x 2x 2x 2x 2x 13
988:2x 2x 13x 19
646:2x 17x 19
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 13x 19 = 1976
Therefore, the value for common factors is 1976.
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 = 221436314112/(2x1976)
LCM = 221436314112/3952
LCM = 56031456
Thus, we can understand that the LCM of 834,416,988,646 is 56031456.
