Given numbers are 405,123,845,100,273
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 405,123,845,100,273 is 392874300.
Find LCM of 405,123,845,100,273 with Prime Factorization
3 | 405, 123, 845, 100, 273 |
5 | 135, 41, 845, 100, 91 |
13 | 27, 41, 169, 20, 91 |
27, 41, 13, 20, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 13 x 27 x 41 x 13 x 20 x 7 = 392874300
Therefore, the lowest common multiple of 405,123,845,100,273 is 392874300.
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 123 x 845 x 100 x 273 = 1149157327500
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
123 : 1, 3, 41, 123
845 : 1, 5, 13, 65, 169, 845
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
273 : 1, 3, 7, 13, 21, 39, 91, 273
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,123,845,100,273, is 1.
Now, the common factors can be found like this.
405:3x 3x 3x 3x 5
123:3x 41
845:5x 13x 13
100:2x 2x 5x 5
273:3x 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 5x 5x 13 = 2925
Therefore, the value for common factors is 2925.
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 = 1149157327500/(1x2925)
LCM = 1149157327500/2925
LCM = 392874300
Thus, we can understand that the LCM of 405,123,845,100,273 is 392874300.
