Given numbers are 723,455,631,979,623
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 723,455,631,979,623 is 203217799785.
Find LCM of 723,455,631,979,623 with Prime Factorization
| 7 | 723, 455, 631, 979, 623 |
| 89 | 723, 65, 631, 979, 89 |
| 723, 65, 631, 11, 1 |
Multiply the prime numbers at the bottom and the left side.
7 x 89 x 723 x 65 x 631 x 11 x 1 = 203217799785
Therefore, the lowest common multiple of 723,455,631,979,623 is 203217799785.
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.
723 x 455 x 631 x 979 x 623 = 126604689266055
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.
723 : 1, 3, 241, 723
455 : 1, 5, 7, 13, 35, 65, 91, 455
631 : 1, 631
979 : 1, 11, 89, 979
623 : 1, 7, 89, 623
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 723,455,631,979,623, is 1.
Now, the common factors can be found like this.
723:3x 241
455:5x 7x 13
631:631
979:11x 89
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.
7x 89 = 623
Therefore, the value for common factors is 623.
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 = 126604689266055/(1x623)
LCM = 126604689266055/623
LCM = 203217799785
Thus, we can understand that the LCM of 723,455,631,979,623 is 203217799785.
