Given numbers are 903,351,343,663,455
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 903,351,343,663,455 is 440036415.
Find LCM of 903,351,343,663,455 with Prime Factorization
| 3 | 903, 351, 343, 663, 455 |
| 7 | 301, 117, 343, 221, 455 |
| 13 | 43, 117, 49, 221, 65 |
| 43, 9, 49, 17, 5 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 13 x 43 x 9 x 49 x 17 x 5 = 440036415
Therefore, the lowest common multiple of 903,351,343,663,455 is 440036415.
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.
903 x 351 x 343 x 663 x 455 = 32795473973535
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.
903 : 1, 3, 7, 21, 43, 129, 301, 903
351 : 1, 3, 9, 13, 27, 39, 117, 351
343 : 1, 7, 49, 343
663 : 1, 3, 13, 17, 39, 51, 221, 663
455 : 1, 5, 7, 13, 35, 65, 91, 455
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 903,351,343,663,455, is 1.
Now, the common factors can be found like this.
903:3x 7x 43
351:3x 3x 3x 13
343:7x 7x 7
663:3x 13x 17
455:5x 7x 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 7x 7x 13x 13 = 74529
Therefore, the value for common factors is 74529.
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 = 32795473973535/(1x74529)
LCM = 32795473973535/74529
LCM = 440036415
Thus, we can understand that the LCM of 903,351,343,663,455 is 440036415.
