Given numbers are 405,836,541,912
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 405,836,541,912 is 732687120.
Find LCM of 405,836,541,912 with Prime Factorization
| 2 | 405, 836, 541, 912 |
| 2 | 405, 418, 541, 456 |
| 3 | 405, 209, 541, 228 |
| 19 | 135, 209, 541, 76 |
| 135, 11, 541, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 19 x 135 x 11 x 541 x 4 = 732687120
Therefore, the lowest common multiple of 405,836,541,912 is 732687120.
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.
405 x 836 x 541 x 912 = 167052663360
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.
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
541 : 1, 541
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,836,541,912, is 1.
Now, the common factors can be found like this.
405:3x 3x 3x 3x 5
836:2x 2x 11x 19
541:541
912:2x 2x 2x 2x 3x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 19 = 228
Therefore, the value for common factors is 228.
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 = 167052663360/(1x228)
LCM = 167052663360/228
LCM = 732687120
Thus, we can understand that the LCM of 405,836,541,912 is 732687120.
