Given numbers are 693,341,405,429
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 693,341,405,429 is 12567555.
Find LCM of 693,341,405,429 with Prime Factorization
| 3 | 693, 341, 405, 429 |
| 3 | 231, 341, 135, 143 |
| 11 | 77, 341, 45, 143 |
| 7, 31, 45, 13 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 11 x 7 x 31 x 45 x 13 = 12567555
Therefore, the lowest common multiple of 693,341,405,429 is 12567555.
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.
693 x 341 x 405 x 429 = 41058202185
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.
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
341 : 1, 11, 31, 341
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
429 : 1, 3, 11, 13, 33, 39, 143, 429
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 693,341,405,429, is 1.
Now, the common factors can be found like this.
693:3x 3x 7x 11
341:11x 31
405:3x 3x 3x 3x 5
429:3x 11x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 11x 11 = 3267
Therefore, the value for common factors is 3267.
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 = 41058202185/(1x3267)
LCM = 41058202185/3267
LCM = 12567555
Thus, we can understand that the LCM of 693,341,405,429 is 12567555.
