Given numbers are 511,801,786,189
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 511,801,786,189 is 321718446.
Find LCM of 511,801,786,189 with Prime Factorization
| 3 | 511, 801, 786, 189 |
| 3 | 511, 267, 262, 63 |
| 7 | 511, 89, 262, 21 |
| 73, 89, 262, 3 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 73 x 89 x 262 x 3 = 321718446
Therefore, the lowest common multiple of 511,801,786,189 is 321718446.
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.
511 x 801 x 786 x 189 = 60804786294
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.
511 : 1, 7, 73, 511
801 : 1, 3, 9, 89, 267, 801
786 : 1, 2, 3, 6, 131, 262, 393, 786
189 : 1, 3, 7, 9, 21, 27, 63, 189
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 511,801,786,189, is 1.
Now, the common factors can be found like this.
511:7x 73
801:3x 3x 89
786:2x 3x 131
189:3x 3x 3x 7
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 7 = 189
Therefore, the value for common factors is 189.
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 = 60804786294/(1x189)
LCM = 60804786294/189
LCM = 321718446
Thus, we can understand that the LCM of 511,801,786,189 is 321718446.
