Given numbers are 405,909,943,252,758
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 405,909,943,252,758 is 409341079980.
Find LCM of 405,909,943,252,758 with Prime Factorization
| 2 | 405, 909, 943, 252, 758 |
| 3 | 405, 909, 943, 126, 379 |
| 3 | 135, 303, 943, 42, 379 |
| 45, 101, 943, 14, 379 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 45 x 101 x 943 x 14 x 379 = 409341079980
Therefore, the lowest common multiple of 405,909,943,252,758 is 409341079980.
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 909 x 943 x 252 x 758 = 66313254956760
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
909 : 1, 3, 9, 101, 303, 909
943 : 1, 23, 41, 943
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
758 : 1, 2, 379, 758
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,909,943,252,758, is 1.
Now, the common factors can be found like this.
405:3x 3x 3x 3x 5
909:3x 3x 101
943:23x 41
252:2x 2x 3x 3x 7
758:2x 379
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 3 = 162
Therefore, the value for common factors is 162.
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 = 66313254956760/(1x162)
LCM = 66313254956760/162
LCM = 409341079980
Thus, we can understand that the LCM of 405,909,943,252,758 is 409341079980.
