Given numbers are 966,115,721,946,623
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 966,115,721,946,623 is 20942836530.
Find LCM of 966,115,721,946,623 with Prime Factorization
| 2 | 966, 115, 721, 946, 623 |
| 7 | 483, 115, 721, 473, 623 |
| 23 | 69, 115, 103, 473, 89 |
| 3, 5, 103, 473, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 23 x 3 x 5 x 103 x 473 x 89 = 20942836530
Therefore, the lowest common multiple of 966,115,721,946,623 is 20942836530.
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.
966 x 115 x 721 x 946 x 623 = 47205153538620
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.
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
115 : 1, 5, 23, 115
721 : 1, 7, 103, 721
946 : 1, 2, 11, 22, 43, 86, 473, 946
623 : 1, 7, 89, 623
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 966,115,721,946,623, is 1.
Now, the common factors can be found like this.
966:2x 3x 7x 23
115:5x 23
721:7x 103
946:2x 11x 43
623:7x 89
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 7x 23 = 2254
Therefore, the value for common factors is 2254.
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 = 47205153538620/(1x2254)
LCM = 47205153538620/2254
LCM = 20942836530
Thus, we can understand that the LCM of 966,115,721,946,623 is 20942836530.
