Given numbers are 841,102,753,666,990
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 841,102,753,666,990 is 131448476610.
Find LCM of 841,102,753,666,990 with Prime Factorization
| 2 | 841, 102, 753, 666, 990 |
| 3 | 841, 51, 753, 333, 495 |
| 3 | 841, 17, 251, 111, 165 |
| 841, 17, 251, 37, 55 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 841 x 17 x 251 x 37 x 55 = 131448476610
Therefore, the lowest common multiple of 841,102,753,666,990 is 131448476610.
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.
841 x 102 x 753 x 666 x 990 = 42589306421640
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.
841 : 1, 29, 841
102 : 1, 2, 3, 6, 17, 34, 51, 102
753 : 1, 3, 251, 753
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 841,102,753,666,990, is 1.
Now, the common factors can be found like this.
841:29x 29
102:2x 3x 17
753:3x 251
666:2x 3x 3x 37
990:2x 3x 3x 5x 11
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 3x 3x 3 = 324
Therefore, the value for common factors is 324.
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 = 42589306421640/(1x324)
LCM = 42589306421640/324
LCM = 131448476610
Thus, we can understand that the LCM of 841,102,753,666,990 is 131448476610.
