Given numbers are 385,647,326,256,913
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 385,647,326,256,913 is 862721601280.
Find LCM of 385,647,326,256,913 with Prime Factorization
| 2 | 385, 647, 326, 256, 913 |
| 11 | 385, 647, 163, 128, 913 |
| 35, 647, 163, 128, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 35 x 647 x 163 x 128 x 83 = 862721601280
Therefore, the lowest common multiple of 385,647,326,256,913 is 862721601280.
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.
385 x 647 x 326 x 256 x 913 = 18979875228160
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.
385 : 1, 5, 7, 11, 35, 55, 77, 385
647 : 1, 647
326 : 1, 2, 163, 326
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
913 : 1, 11, 83, 913
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 385,647,326,256,913, is 1.
Now, the common factors can be found like this.
385:5x 7x 11
647:647
326:2x 163
256:2x 2x 2x 2x 2x 2x 2x 2
913:11x 83
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11 = 22
Therefore, the value for common factors is 22.
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 = 18979875228160/(1x22)
LCM = 18979875228160/22
LCM = 862721601280
Thus, we can understand that the LCM of 385,647,326,256,913 is 862721601280.
