Given numbers are 676,676,940,408
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 676,676,940,408 is 16203720.
Find LCM of 676,676,940,408 with Prime Factorization
| 2 | 676, 676, 940, 408 |
| 2 | 338, 338, 470, 204 |
| 13 | 169, 169, 235, 102 |
| 13 | 13, 13, 235, 102 |
| 1, 1, 235, 102 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 13 x 1 x 1 x 235 x 102 = 16203720
Therefore, the lowest common multiple of 676,676,940,408 is 16203720.
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 676 x 940 x 408 = 175259435520
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
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 676,676,940,408, is 4.
Now, the common factors can be found like this.
676:2x 2x 13x 13
676:2x 2x 13x 13
940:2x 2x 5x 47
408:2x 2x 2x 3x 17
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 13x 13 = 2704
Therefore, the value for common factors is 2704.
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 = 175259435520/(4x2704)
LCM = 175259435520/10816
LCM = 16203720
Thus, we can understand that the LCM of 676,676,940,408 is 16203720.
