Given numbers are 635,903,945
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 635,903,945 is 5160645.
Find LCM of 635,903,945 with Prime Factorization
| 3 | 635, 903, 945 |
| 5 | 635, 301, 315 |
| 7 | 127, 301, 63 |
| 127, 43, 9 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 127 x 43 x 9 = 5160645
Therefore, the lowest common multiple of 635,903,945 is 5160645.
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.
635 x 903 x 945 = 541867725
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.
635 : 1, 5, 127, 635
903 : 1, 3, 7, 21, 43, 129, 301, 903
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 635,903,945, is 1.
Now, the common factors can be found like this.
635:5x 127
903:3x 7x 43
945:3x 3x 3x 5x 7
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 7 = 105
Therefore, the value for common factors is 105.
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 = 541867725/(1x105)
LCM = 541867725/105
LCM = 5160645
Thus, we can understand that the LCM of 635,903,945 is 5160645.
