Given numbers are 190,861,493,779
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 190,861,493,779 is 80649870.
Find LCM of 190,861,493,779 with Prime Factorization
| 19 | 190, 861, 493, 779 |
| 41 | 10, 861, 493, 41 |
| 10, 21, 493, 1 |
Multiply the prime numbers at the bottom and the left side.
19 x 41 x 10 x 21 x 493 x 1 = 80649870
Therefore, the lowest common multiple of 190,861,493,779 is 80649870.
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.
190 x 861 x 493 x 779 = 62826248730
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.
190 : 1, 2, 5, 10, 19, 38, 95, 190
861 : 1, 3, 7, 21, 41, 123, 287, 861
493 : 1, 17, 29, 493
779 : 1, 19, 41, 779
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 190,861,493,779, is 1.
Now, the common factors can be found like this.
190:2x 5x 19
861:3x 7x 41
493:17x 29
779:19x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19x 41 = 779
Therefore, the value for common factors is 779.
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 = 62826248730/(1x779)
LCM = 62826248730/779
LCM = 80649870
Thus, we can understand that the LCM of 190,861,493,779 is 80649870.
