Given numbers are 405,777,639,402,447
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 405,777,639,402,447 is 148697683470.
Find LCM of 405,777,639,402,447 with Prime Factorization
3 | 405, 777, 639, 402, 447 |
3 | 135, 259, 213, 134, 149 |
45, 259, 71, 134, 149 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 45 x 259 x 71 x 134 x 149 = 148697683470
Therefore, the lowest common multiple of 405,777,639,402,447 is 148697683470.
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 777 x 639 x 402 x 447 = 36133537083210
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
777 : 1, 3, 7, 21, 37, 111, 259, 777
639 : 1, 3, 9, 71, 213, 639
402 : 1, 2, 3, 6, 67, 134, 201, 402
447 : 1, 3, 149, 447
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,777,639,402,447, is 3.
Now, the common factors can be found like this.
405:3x 3x 3x 3x 5
777:3x 7x 37
639:3x 3x 71
402:2x 3x 67
447:3x 149
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 3 = 81
Therefore, the value for common factors is 81.
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 = 36133537083210/(3x81)
LCM = 36133537083210/243
LCM = 148697683470
Thus, we can understand that the LCM of 405,777,639,402,447 is 148697683470.
