Given numbers are 206,165,784,109
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 206,165,784,109 is 1452324720.
Find LCM of 206,165,784,109 with Prime Factorization
| 2 | 206, 165, 784, 109 |
| 103, 165, 392, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 103 x 165 x 392 x 109 = 1452324720
Therefore, the lowest common multiple of 206,165,784,109 is 1452324720.
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.
206 x 165 x 784 x 109 = 2904649440
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.
206 : 1, 2, 103, 206
165 : 1, 3, 5, 11, 15, 33, 55, 165
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
109 : 1, 109
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 206,165,784,109, is 1.
Now, the common factors can be found like this.
206:2x 103
165:3x 5x 11
784:2x 2x 2x 2x 7x 7
109:109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 2904649440/(1x2)
LCM = 2904649440/2
LCM = 1452324720
Thus, we can understand that the LCM of 206,165,784,109 is 1452324720.
