Given numbers are 807,308,979,203,857
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 807,308,979,203,857 is 549785241852.
Find LCM of 807,308,979,203,857 with Prime Factorization
| 7 | 807, 308, 979, 203, 857 |
| 11 | 807, 44, 979, 29, 857 |
| 807, 4, 89, 29, 857 |
Multiply the prime numbers at the bottom and the left side.
7 x 11 x 807 x 4 x 89 x 29 x 857 = 549785241852
Therefore, the lowest common multiple of 807,308,979,203,857 is 549785241852.
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.
807 x 308 x 979 x 203 x 857 = 42333463622604
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.
807 : 1, 3, 269, 807
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
979 : 1, 11, 89, 979
203 : 1, 7, 29, 203
857 : 1, 857
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 807,308,979,203,857, is 1.
Now, the common factors can be found like this.
807:3x 269
308:2x 2x 7x 11
979:11x 89
203:7x 29
857:857
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 11 = 77
Therefore, the value for common factors is 77.
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 = 42333463622604/(1x77)
LCM = 42333463622604/77
LCM = 549785241852
Thus, we can understand that the LCM of 807,308,979,203,857 is 549785241852.
