Given numbers are 275,783,687,805,782
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 275,783,687,805,782 is 269919792450.
Find LCM of 275,783,687,805,782 with Prime Factorization
| 3 | 275, 783, 687, 805, 782 |
| 5 | 275, 261, 229, 805, 782 |
| 23 | 55, 261, 229, 161, 782 |
| 55, 261, 229, 7, 34 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 23 x 55 x 261 x 229 x 7 x 34 = 269919792450
Therefore, the lowest common multiple of 275,783,687,805,782 is 269919792450.
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.
275 x 783 x 687 x 805 x 782 = 93122328395250
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.
275 : 1, 5, 11, 25, 55, 275
783 : 1, 3, 9, 27, 29, 87, 261, 783
687 : 1, 3, 229, 687
805 : 1, 5, 7, 23, 35, 115, 161, 805
782 : 1, 2, 17, 23, 34, 46, 391, 782
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 275,783,687,805,782, is 1.
Now, the common factors can be found like this.
275:5x 5x 11
783:3x 3x 3x 29
687:3x 229
805:5x 7x 23
782:2x 17x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 23 = 345
Therefore, the value for common factors is 345.
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 = 93122328395250/(1x345)
LCM = 93122328395250/345
LCM = 269919792450
Thus, we can understand that the LCM of 275,783,687,805,782 is 269919792450.
