Given numbers are 556,774,871,806
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 556,774,871,806 is 5809859172.
Find LCM of 556,774,871,806 with Prime Factorization
| 2 | 556, 774, 871, 806 |
| 13 | 278, 387, 871, 403 |
| 278, 387, 67, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 278 x 387 x 67 x 31 = 5809859172
Therefore, the lowest common multiple of 556,774,871,806 is 5809859172.
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.
556 x 774 x 871 x 806 = 302112676944
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.
556 : 1, 2, 4, 139, 278, 556
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
871 : 1, 13, 67, 871
806 : 1, 2, 13, 26, 31, 62, 403, 806
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 556,774,871,806, is 1.
Now, the common factors can be found like this.
556:2x 2x 139
774:2x 3x 3x 43
871:13x 67
806:2x 13x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 13 = 52
Therefore, the value for common factors is 52.
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 = 302112676944/(1x52)
LCM = 302112676944/52
LCM = 5809859172
Thus, we can understand that the LCM of 556,774,871,806 is 5809859172.
