Given numbers are 849,810,369,646
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 849,810,369,646 is 3035692890.
Find LCM of 849,810,369,646 with Prime Factorization
| 2 | 849, 810, 369, 646 |
| 3 | 849, 405, 369, 323 |
| 3 | 283, 135, 123, 323 |
| 283, 45, 41, 323 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 283 x 45 x 41 x 323 = 3035692890
Therefore, the lowest common multiple of 849,810,369,646 is 3035692890.
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.
849 x 810 x 369 x 646 = 163927416060
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.
849 : 1, 3, 283, 849
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
369 : 1, 3, 9, 41, 123, 369
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 849,810,369,646, is 1.
Now, the common factors can be found like this.
849:3x 283
810:2x 3x 3x 3x 3x 5
369:3x 3x 41
646:2x 17x 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 3x 3x 3 = 54
Therefore, the value for common factors is 54.
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 = 163927416060/(1x54)
LCM = 163927416060/54
LCM = 3035692890
Thus, we can understand that the LCM of 849,810,369,646 is 3035692890.
