Given numbers are 191,428,616,806
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 191,428,616,806 is 5073444376.
Find LCM of 191,428,616,806 with Prime Factorization
| 2 | 191, 428, 616, 806 |
| 2 | 191, 214, 308, 403 |
| 191, 107, 154, 403 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 191 x 107 x 154 x 403 = 5073444376
Therefore, the lowest common multiple of 191,428,616,806 is 5073444376.
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.
191 x 428 x 616 x 806 = 40587555008
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.
191 : 1, 191
428 : 1, 2, 4, 107, 214, 428
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
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 191,428,616,806, is 1.
Now, the common factors can be found like this.
191:191
428:2x 2x 107
616:2x 2x 2x 7x 11
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 2 = 8
Therefore, the value for common factors is 8.
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 = 40587555008/(1x8)
LCM = 40587555008/8
LCM = 5073444376
Thus, we can understand that the LCM of 191,428,616,806 is 5073444376.
