Given numbers are 649,889,605,811
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 649,889,605,811 is 25735345405.
Find LCM of 649,889,605,811 with Prime Factorization
| 11 | 649, 889, 605, 811 |
| 59, 889, 55, 811 |
Multiply the prime numbers at the bottom and the left side.
11 x 59 x 889 x 55 x 811 = 25735345405
Therefore, the lowest common multiple of 649,889,605,811 is 25735345405.
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.
649 x 889 x 605 x 811 = 283088799455
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.
649 : 1, 11, 59, 649
889 : 1, 7, 127, 889
605 : 1, 5, 11, 55, 121, 605
811 : 1, 811
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,889,605,811, is 1.
Now, the common factors can be found like this.
649:11x 59
889:7x 127
605:5x 11x 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.
11 = 11
Therefore, the value for common factors is 11.
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 = 283088799455/(1x11)
LCM = 283088799455/11
LCM = 25735345405
Thus, we can understand that the LCM of 649,889,605,811 is 25735345405.
