Given numbers are 605,381,899,899
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 605,381,899,899 is 207223995.
Find LCM of 605,381,899,899 with Prime Factorization
| 29 | 605, 381, 899, 899 |
| 31 | 605, 381, 31, 31 |
| 605, 381, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
29 x 31 x 605 x 381 x 1 x 1 = 207223995
Therefore, the lowest common multiple of 605,381,899,899 is 207223995.
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.
605 x 381 x 899 x 899 = 186294371505
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.
605 : 1, 5, 11, 55, 121, 605
381 : 1, 3, 127, 381
899 : 1, 29, 31, 899
899 : 1, 29, 31, 899
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,381,899,899, is 1.
Now, the common factors can be found like this.
605:5x 11x 11
381:3x 127
899:29x 31
899:29x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
29x 31 = 899
Therefore, the value for common factors is 899.
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 = 186294371505/(1x899)
LCM = 186294371505/899
LCM = 207223995
Thus, we can understand that the LCM of 605,381,899,899 is 207223995.
