Given numbers are 418,836,689,467
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 418,836,689,467 is 268993868.
Find LCM of 418,836,689,467 with Prime Factorization
| 2 | 418, 836, 689, 467 |
| 11 | 209, 418, 689, 467 |
| 19 | 19, 38, 689, 467 |
| 1, 2, 689, 467 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 19 x 1 x 2 x 689 x 467 = 268993868
Therefore, the lowest common multiple of 418,836,689,467 is 268993868.
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.
418 x 836 x 689 x 467 = 112439436824
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.
418 : 1, 2, 11, 19, 22, 38, 209, 418
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
689 : 1, 13, 53, 689
467 : 1, 467
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,836,689,467, is 1.
Now, the common factors can be found like this.
418:2x 11x 19
836:2x 2x 11x 19
689:13x 53
467:467
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 19 = 418
Therefore, the value for common factors is 418.
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 = 112439436824/(1x418)
LCM = 112439436824/418
LCM = 268993868
Thus, we can understand that the LCM of 418,836,689,467 is 268993868.
