Given numbers are 445,861,997,623
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 445,861,997,623 is 381995565.
Find LCM of 445,861,997,623 with Prime Factorization
| 7 | 445, 861, 997, 623 |
| 89 | 445, 123, 997, 89 |
| 5, 123, 997, 1 |
Multiply the prime numbers at the bottom and the left side.
7 x 89 x 5 x 123 x 997 x 1 = 381995565
Therefore, the lowest common multiple of 445,861,997,623 is 381995565.
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.
445 x 861 x 997 x 623 = 237983236995
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.
445 : 1, 5, 89, 445
861 : 1, 3, 7, 21, 41, 123, 287, 861
997 : 1, 997
623 : 1, 7, 89, 623
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 445,861,997,623, is 1.
Now, the common factors can be found like this.
445:5x 89
861:3x 7x 41
997:997
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 = 237983236995/(1x623)
LCM = 237983236995/623
LCM = 381995565
Thus, we can understand that the LCM of 445,861,997,623 is 381995565.
