Given numbers are 338,676,561,814
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 338,676,561,814 is 14031732.
Find LCM of 338,676,561,814 with Prime Factorization
| 2 | 338, 676, 561, 814 |
| 11 | 169, 338, 561, 407 |
| 13 | 169, 338, 51, 37 |
| 13 | 13, 26, 51, 37 |
| 1, 2, 51, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 13 x 13 x 1 x 2 x 51 x 37 = 14031732
Therefore, the lowest common multiple of 338,676,561,814 is 14031732.
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.
338 x 676 x 561 x 814 = 104339959152
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.
338 : 1, 2, 13, 26, 169, 338
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
561 : 1, 3, 11, 17, 33, 51, 187, 561
814 : 1, 2, 11, 22, 37, 74, 407, 814
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 338,676,561,814, is 1.
Now, the common factors can be found like this.
338:2x 13x 13
676:2x 2x 13x 13
561:3x 11x 17
814:2x 11x 37
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 11x 13x 13 = 7436
Therefore, the value for common factors is 7436.
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 = 104339959152/(1x7436)
LCM = 104339959152/7436
LCM = 14031732
Thus, we can understand that the LCM of 338,676,561,814 is 14031732.
