Given numbers are 391,806,170,955,100
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 391,806,170,955,100 is 3009644300.
Find LCM of 391,806,170,955,100 with Prime Factorization
| 2 | 391, 806, 170, 955, 100 |
| 5 | 391, 403, 85, 955, 50 |
| 17 | 391, 403, 17, 191, 10 |
| 23, 403, 1, 191, 10 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 23 x 403 x 1 x 191 x 10 = 3009644300
Therefore, the lowest common multiple of 391,806,170,955,100 is 3009644300.
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.
391 x 806 x 170 x 955 x 100 = 5116395310000
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.
391 : 1, 17, 23, 391
806 : 1, 2, 13, 26, 31, 62, 403, 806
170 : 1, 2, 5, 10, 17, 34, 85, 170
955 : 1, 5, 191, 955
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,806,170,955,100, is 1.
Now, the common factors can be found like this.
391:17x 23
806:2x 13x 31
170:2x 5x 17
955:5x 191
100:2x 2x 5x 5
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 5x 5x 17 = 1700
Therefore, the value for common factors is 1700.
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 = 5116395310000/(1x1700)
LCM = 5116395310000/1700
LCM = 3009644300
Thus, we can understand that the LCM of 391,806,170,955,100 is 3009644300.
