Given numbers are 665,449,976,105,305
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 665,449,976,105,305 is 874256880.
Find LCM of 665,449,976,105,305 with Prime Factorization
5 | 665, 449, 976, 105, 305 |
7 | 133, 449, 976, 21, 61 |
61 | 19, 449, 976, 3, 61 |
19, 449, 16, 3, 1 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 61 x 19 x 449 x 16 x 3 x 1 = 874256880
Therefore, the lowest common multiple of 665,449,976,105,305 is 874256880.
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.
665 x 449 x 976 x 105 x 305 = 9332692194000
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.
665 : 1, 5, 7, 19, 35, 95, 133, 665
449 : 1, 449
976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976
105 : 1, 3, 5, 7, 15, 21, 35, 105
305 : 1, 5, 61, 305
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,449,976,105,305, is 1.
Now, the common factors can be found like this.
665:5x 7x 19
449:449
976:2x 2x 2x 2x 61
105:3x 5x 7
305:5x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5x 7x 61 = 10675
Therefore, the value for common factors is 10675.
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 = 9332692194000/(1x10675)
LCM = 9332692194000/10675
LCM = 874256880
Thus, we can understand that the LCM of 665,449,976,105,305 is 874256880.
