Given numbers are 844,416,921,694,243
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 844,416,921,694,243 is 2272217549472.
Find LCM of 844,416,921,694,243 with Prime Factorization
| 2 | 844, 416, 921, 694, 243 |
| 2 | 422, 208, 921, 347, 243 |
| 3 | 211, 104, 921, 347, 243 |
| 211, 104, 307, 347, 81 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 211 x 104 x 307 x 347 x 81 = 2272217549472
Therefore, the lowest common multiple of 844,416,921,694,243 is 2272217549472.
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.
844 x 416 x 921 x 694 x 243 = 54533221187328
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.
844 : 1, 2, 4, 211, 422, 844
416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416
921 : 1, 3, 307, 921
694 : 1, 2, 347, 694
243 : 1, 3, 9, 27, 81, 243
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 844,416,921,694,243, is 1.
Now, the common factors can be found like this.
844:2x 2x 211
416:2x 2x 2x 2x 2x 13
921:3x 307
694:2x 347
243:3x 3x 3x 3x 3
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 2x 3 = 24
Therefore, the value for common factors is 24.
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 = 54533221187328/(1x24)
LCM = 54533221187328/24
LCM = 2272217549472
Thus, we can understand that the LCM of 844,416,921,694,243 is 2272217549472.
