Given numbers are 676,362,845,128
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 676,362,845,128 is 19576960.
Find LCM of 676,362,845,128 with Prime Factorization
| 2 | 676, 362, 845, 128 |
| 2 | 338, 181, 845, 64 |
| 13 | 169, 181, 845, 32 |
| 13 | 13, 181, 65, 32 |
| 1, 181, 5, 32 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 13 x 1 x 181 x 5 x 32 = 19576960
Therefore, the lowest common multiple of 676,362,845,128 is 19576960.
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.
676 x 362 x 845 x 128 = 26468049920
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.
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
362 : 1, 2, 181, 362
845 : 1, 5, 13, 65, 169, 845
128 : 1, 2, 4, 8, 16, 32, 64, 128
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 676,362,845,128, is 1.
Now, the common factors can be found like this.
676:2x 2x 13x 13
362:2x 181
845:5x 13x 13
128:2x 2x 2x 2x 2x 2x 2
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 13 = 1352
Therefore, the value for common factors is 1352.
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 = 26468049920/(1x1352)
LCM = 26468049920/1352
LCM = 19576960
Thus, we can understand that the LCM of 676,362,845,128 is 19576960.
