Given numbers are 481,963,963,726,721
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 481,963,963,726,721 is 80820585846.
Find LCM of 481,963,963,726,721 with Prime Factorization
| 3 | 481, 963, 963, 726, 721 |
| 3 | 481, 321, 321, 242, 721 |
| 107 | 481, 107, 107, 242, 721 |
| 481, 1, 1, 242, 721 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 107 x 481 x 1 x 1 x 242 x 721 = 80820585846
Therefore, the lowest common multiple of 481,963,963,726,721 is 80820585846.
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.
481 x 963 x 963 x 726 x 721 = 233490672509094
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.
481 : 1, 13, 37, 481
963 : 1, 3, 9, 107, 321, 963
963 : 1, 3, 9, 107, 321, 963
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 481,963,963,726,721, is 1.
Now, the common factors can be found like this.
481:13x 37
963:3x 3x 107
963:3x 3x 107
726:2x 3x 11x 11
721:7x 103
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 107 = 2889
Therefore, the value for common factors is 2889.
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 = 233490672509094/(1x2889)
LCM = 233490672509094/2889
LCM = 80820585846
Thus, we can understand that the LCM of 481,963,963,726,721 is 80820585846.
