Given numbers are 721,615,887,206
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,615,887,206 is 786618210.
Find LCM of 721,615,887,206 with Prime Factorization
| 103 | 721, 615, 887, 206 |
| 7, 615, 887, 2 |
Multiply the prime numbers at the bottom and the left side.
103 x 7 x 615 x 887 x 2 = 786618210
Therefore, the lowest common multiple of 721,615,887,206 is 786618210.
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.
721 x 615 x 887 x 206 = 81021675630
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.
721 : 1, 7, 103, 721
615 : 1, 3, 5, 15, 41, 123, 205, 615
887 : 1, 887
206 : 1, 2, 103, 206
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,615,887,206, is 1.
Now, the common factors can be found like this.
721:7x 103
615:3x 5x 41
887:887
206:2x 103
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
103 = 103
Therefore, the value for common factors is 103.
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 = 81021675630/(1x103)
LCM = 81021675630/103
LCM = 786618210
Thus, we can understand that the LCM of 721,615,887,206 is 786618210.
