Given numbers are 837,285,921,162,144
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 837,285,921,162,144 is 1171733040.
Find LCM of 837,285,921,162,144 with Prime Factorization
| 2 | 837, 285, 921, 162, 144 |
| 3 | 837, 285, 921, 81, 72 |
| 3 | 279, 95, 307, 27, 24 |
| 3 | 93, 95, 307, 9, 8 |
| 31, 95, 307, 3, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 31 x 95 x 307 x 3 x 8 = 1171733040
Therefore, the lowest common multiple of 837,285,921,162,144 is 1171733040.
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.
837 x 285 x 921 x 162 x 144 = 5125160316960
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.
837 : 1, 3, 9, 27, 31, 93, 279, 837
285 : 1, 3, 5, 15, 19, 57, 95, 285
921 : 1, 3, 307, 921
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 837,285,921,162,144, is 3.
Now, the common factors can be found like this.
837:3x 3x 3x 31
285:3x 5x 19
921:3x 307
162:2x 3x 3x 3x 3
144:2x 2x 2x 2x 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 3x 3x 3x 3x 3x 3 = 1458
Therefore, the value for common factors is 1458.
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 = 5125160316960/(3x1458)
LCM = 5125160316960/4374
LCM = 1171733040
Thus, we can understand that the LCM of 837,285,921,162,144 is 1171733040.
