Given numbers are 471,873,969,345,931
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 471,873,969,345,931 is 249465411405.
Find LCM of 471,873,969,345,931 with Prime Factorization
| 3 | 471, 873, 969, 345, 931 |
| 19 | 157, 291, 323, 115, 931 |
| 157, 291, 17, 115, 49 |
Multiply the prime numbers at the bottom and the left side.
3 x 19 x 157 x 291 x 17 x 115 x 49 = 249465411405
Therefore, the lowest common multiple of 471,873,969,345,931 is 249465411405.
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.
471 x 873 x 969 x 345 x 931 = 127975756050765
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.
471 : 1, 3, 157, 471
873 : 1, 3, 9, 97, 291, 873
969 : 1, 3, 17, 19, 51, 57, 323, 969
345 : 1, 3, 5, 15, 23, 69, 115, 345
931 : 1, 7, 19, 49, 133, 931
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 471,873,969,345,931, is 1.
Now, the common factors can be found like this.
471:3x 157
873:3x 3x 97
969:3x 17x 19
345:3x 5x 23
931:7x 7x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 19 = 513
Therefore, the value for common factors is 513.
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 = 127975756050765/(1x513)
LCM = 127975756050765/513
LCM = 249465411405
Thus, we can understand that the LCM of 471,873,969,345,931 is 249465411405.
