Given numbers are 105,812,828,807
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 105,812,828,807 is 226072980.
Find LCM of 105,812,828,807 with Prime Factorization
| 2 | 105, 812, 828, 807 |
| 2 | 105, 406, 414, 807 |
| 3 | 105, 203, 207, 807 |
| 7 | 35, 203, 69, 269 |
| 5, 29, 69, 269 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 5 x 29 x 69 x 269 = 226072980
Therefore, the lowest common multiple of 105,812,828,807 is 226072980.
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.
105 x 812 x 828 x 807 = 56970390960
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.
105 : 1, 3, 5, 7, 15, 21, 35, 105
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
807 : 1, 3, 269, 807
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 105,812,828,807, is 1.
Now, the common factors can be found like this.
105:3x 5x 7
812:2x 2x 7x 29
828:2x 2x 3x 3x 23
807:3x 269
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 3x 3x 7 = 252
Therefore, the value for common factors is 252.
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 = 56970390960/(1x252)
LCM = 56970390960/252
LCM = 226072980
Thus, we can understand that the LCM of 105,812,828,807 is 226072980.
