Given numbers are 705,945,141,903,103
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 705,945,141,903,103 is 196714035.
Find LCM of 705,945,141,903,103 with Prime Factorization
| 3 | 705, 945, 141, 903, 103 |
| 5 | 235, 315, 47, 301, 103 |
| 7 | 47, 63, 47, 301, 103 |
| 47 | 47, 9, 47, 43, 103 |
| 1, 9, 1, 43, 103 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 47 x 1 x 9 x 1 x 43 x 103 = 196714035
Therefore, the lowest common multiple of 705,945,141,903,103 is 196714035.
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.
705 x 945 x 141 x 903 x 103 = 8737053864525
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.
705 : 1, 3, 5, 15, 47, 141, 235, 705
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
141 : 1, 3, 47, 141
903 : 1, 3, 7, 21, 43, 129, 301, 903
103 : 1, 103
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 705,945,141,903,103, is 1.
Now, the common factors can be found like this.
705:3x 5x 47
945:3x 3x 3x 5x 7
141:3x 47
903:3x 7x 43
103:103
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 3x 5x 7x 47 = 44415
Therefore, the value for common factors is 44415.
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 = 8737053864525/(1x44415)
LCM = 8737053864525/44415
LCM = 196714035
Thus, we can understand that the LCM of 705,945,141,903,103 is 196714035.
