Given numbers are 215,810,533,361,442
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 215,810,533,361,442 is 113929661430.
Find LCM of 215,810,533,361,442 with Prime Factorization
| 2 | 215, 810, 533, 361, 442 |
| 5 | 215, 405, 533, 361, 221 |
| 13 | 43, 81, 533, 361, 221 |
| 43, 81, 41, 361, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 43 x 81 x 41 x 361 x 17 = 113929661430
Therefore, the lowest common multiple of 215,810,533,361,442 is 113929661430.
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.
215 x 810 x 533 x 361 x 442 = 14810855985900
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.
215 : 1, 5, 43, 215
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
533 : 1, 13, 41, 533
361 : 1, 19, 361
442 : 1, 2, 13, 17, 26, 34, 221, 442
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 215,810,533,361,442, is 1.
Now, the common factors can be found like this.
215:5x 43
810:2x 3x 3x 3x 3x 5
533:13x 41
361:19x 19
442:2x 13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 13 = 130
Therefore, the value for common factors is 130.
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 = 14810855985900/(1x130)
LCM = 14810855985900/130
LCM = 113929661430
Thus, we can understand that the LCM of 215,810,533,361,442 is 113929661430.
