Given numbers are 459,722,921,803
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 459,722,921,803 is 81696566358.
Find LCM of 459,722,921,803 with Prime Factorization
| 3 | 459, 722, 921, 803 |
| 153, 722, 307, 803 |
Multiply the prime numbers at the bottom and the left side.
3 x 153 x 722 x 307 x 803 = 81696566358
Therefore, the lowest common multiple of 459,722,921,803 is 81696566358.
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.
459 x 722 x 921 x 803 = 245089699074
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.
459 : 1, 3, 9, 17, 27, 51, 153, 459
722 : 1, 2, 19, 38, 361, 722
921 : 1, 3, 307, 921
803 : 1, 11, 73, 803
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 459,722,921,803, is 1.
Now, the common factors can be found like this.
459:3x 3x 3x 17
722:2x 19x 19
921:3x 307
803:11x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 245089699074/(1x3)
LCM = 245089699074/3
LCM = 81696566358
Thus, we can understand that the LCM of 459,722,921,803 is 81696566358.
