Given numbers are 991,439,990,888,195
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 991,439,990,888,195 is 828663933240.
Find LCM of 991,439,990,888,195 with Prime Factorization
| 2 | 991, 439, 990, 888, 195 |
| 3 | 991, 439, 495, 444, 195 |
| 5 | 991, 439, 165, 148, 65 |
| 991, 439, 33, 148, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 991 x 439 x 33 x 148 x 13 = 828663933240
Therefore, the lowest common multiple of 991,439,990,888,195 is 828663933240.
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.
991 x 439 x 990 x 888 x 195 = 74579753991600
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.
991 : 1, 991
439 : 1, 439
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
888 : 1, 2, 3, 4, 6, 8, 12, 24, 37, 74, 111, 148, 222, 296, 444, 888
195 : 1, 3, 5, 13, 15, 39, 65, 195
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,439,990,888,195, is 1.
Now, the common factors can be found like this.
991:991
439:439
990:2x 3x 3x 5x 11
888:2x 2x 2x 3x 37
195:3x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5 = 90
Therefore, the value for common factors is 90.
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 = 74579753991600/(1x90)
LCM = 74579753991600/90
LCM = 828663933240
Thus, we can understand that the LCM of 991,439,990,888,195 is 828663933240.
