Given numbers are 565,161,515,215,782
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 565,161,515,215,782 is 13698055490.
Find LCM of 565,161,515,215,782 with Prime Factorization
| 5 | 565, 161, 515, 215, 782 |
| 23 | 113, 161, 103, 43, 782 |
| 113, 7, 103, 43, 34 |
Multiply the prime numbers at the bottom and the left side.
5 x 23 x 113 x 7 x 103 x 43 x 34 = 13698055490
Therefore, the lowest common multiple of 565,161,515,215,782 is 13698055490.
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.
565 x 161 x 515 x 215 x 782 = 7876381906750
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.
565 : 1, 5, 113, 565
161 : 1, 7, 23, 161
515 : 1, 5, 103, 515
215 : 1, 5, 43, 215
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 565,161,515,215,782, is 1.
Now, the common factors can be found like this.
565:5x 113
161:7x 23
515:5x 103
215:5x 43
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.
5x 5x 23 = 575
Therefore, the value for common factors is 575.
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 = 7876381906750/(1x575)
LCM = 7876381906750/575
LCM = 13698055490
Thus, we can understand that the LCM of 565,161,515,215,782 is 13698055490.
