Given numbers are 429,676,905,385
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 429,676,905,385 is 141321180.
Find LCM of 429,676,905,385 with Prime Factorization
| 5 | 429, 676, 905, 385 |
| 11 | 429, 676, 181, 77 |
| 13 | 39, 676, 181, 7 |
| 3, 52, 181, 7 |
Multiply the prime numbers at the bottom and the left side.
5 x 11 x 13 x 3 x 52 x 181 x 7 = 141321180
Therefore, the lowest common multiple of 429,676,905,385 is 141321180.
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.
429 x 676 x 905 x 385 = 101044643700
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.
429 : 1, 3, 11, 13, 33, 39, 143, 429
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
905 : 1, 5, 181, 905
385 : 1, 5, 7, 11, 35, 55, 77, 385
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 429,676,905,385, is 1.
Now, the common factors can be found like this.
429:3x 11x 13
676:2x 2x 13x 13
905:5x 181
385:5x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 11x 13 = 715
Therefore, the value for common factors is 715.
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 = 101044643700/(1x715)
LCM = 101044643700/715
LCM = 141321180
Thus, we can understand that the LCM of 429,676,905,385 is 141321180.
