Given numbers are 812,412,351,973
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 812,412,351,973 is 4080516804.
Find LCM of 812,412,351,973 with Prime Factorization
| 2 | 812, 412, 351, 973 |
| 2 | 406, 206, 351, 973 |
| 7 | 203, 103, 351, 973 |
| 29, 103, 351, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 29 x 103 x 351 x 139 = 4080516804
Therefore, the lowest common multiple of 812,412,351,973 is 4080516804.
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.
812 x 412 x 351 x 973 = 114254470512
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.
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
412 : 1, 2, 4, 103, 206, 412
351 : 1, 3, 9, 13, 27, 39, 117, 351
973 : 1, 7, 139, 973
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 812,412,351,973, is 1.
Now, the common factors can be found like this.
812:2x 2x 7x 29
412:2x 2x 103
351:3x 3x 3x 13
973:7x 139
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 7 = 28
Therefore, the value for common factors is 28.
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 = 114254470512/(1x28)
LCM = 114254470512/28
LCM = 4080516804
Thus, we can understand that the LCM of 812,412,351,973 is 4080516804.
