Given numbers are 554,682,330,434
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 554,682,330,434 is 19835970.
Find LCM of 554,682,330,434 with Prime Factorization
| 2 | 554, 682, 330, 434 |
| 11 | 277, 341, 165, 217 |
| 31 | 277, 31, 15, 217 |
| 277, 1, 15, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 31 x 277 x 1 x 15 x 7 = 19835970
Therefore, the lowest common multiple of 554,682,330,434 is 19835970.
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.
554 x 682 x 330 x 434 = 54112526160
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.
554 : 1, 2, 277, 554
682 : 1, 2, 11, 22, 31, 62, 341, 682
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
434 : 1, 2, 7, 14, 31, 62, 217, 434
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 554,682,330,434, is 2.
Now, the common factors can be found like this.
554:2x 277
682:2x 11x 31
330:2x 3x 5x 11
434:2x 7x 31
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 31 = 1364
Therefore, the value for common factors is 1364.
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 = 54112526160/(2x1364)
LCM = 54112526160/2728
LCM = 19835970
Thus, we can understand that the LCM of 554,682,330,434 is 19835970.
