Given numbers are 429,299,690,728
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 429,299,690,728 is 2762760.
Find LCM of 429,299,690,728 with Prime Factorization
| 2 | 429, 299, 690, 728 |
| 3 | 429, 299, 345, 364 |
| 13 | 143, 299, 115, 364 |
| 23 | 11, 23, 115, 28 |
| 11, 1, 5, 28 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 23 x 11 x 1 x 5 x 28 = 2762760
Therefore, the lowest common multiple of 429,299,690,728 is 2762760.
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 299 x 690 x 728 = 64433088720
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
299 : 1, 13, 23, 299
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 429,299,690,728, is 1.
Now, the common factors can be found like this.
429:3x 11x 13
299:13x 23
690:2x 3x 5x 23
728:2x 2x 2x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 13x 13x 23 = 23322
Therefore, the value for common factors is 23322.
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 = 64433088720/(1x23322)
LCM = 64433088720/23322
LCM = 2762760
Thus, we can understand that the LCM of 429,299,690,728 is 2762760.
