Given numbers are 189,508,308,811
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 189,508,308,811 is 856523052.
Find LCM of 189,508,308,811 with Prime Factorization
| 2 | 189, 508, 308, 811 |
| 2 | 189, 254, 154, 811 |
| 7 | 189, 127, 77, 811 |
| 27, 127, 11, 811 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 27 x 127 x 11 x 811 = 856523052
Therefore, the lowest common multiple of 189,508,308,811 is 856523052.
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.
189 x 508 x 308 x 811 = 23982645456
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.
189 : 1, 3, 7, 9, 21, 27, 63, 189
508 : 1, 2, 4, 127, 254, 508
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
811 : 1, 811
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 189,508,308,811, is 1.
Now, the common factors can be found like this.
189:3x 3x 3x 7
508:2x 2x 127
308:2x 2x 7x 11
811:811
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 = 23982645456/(1x28)
LCM = 23982645456/28
LCM = 856523052
Thus, we can understand that the LCM of 189,508,308,811 is 856523052.
