Given numbers are 991,745,141,305,579
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 991,745,141,305,579 is 1225564531935.
Find LCM of 991,745,141,305,579 with Prime Factorization
| 3 | 991, 745, 141, 305, 579 |
| 5 | 991, 745, 47, 305, 193 |
| 991, 149, 47, 61, 193 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 991 x 149 x 47 x 61 x 193 = 1225564531935
Therefore, the lowest common multiple of 991,745,141,305,579 is 1225564531935.
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 745 x 141 x 305 x 579 = 18383467979025
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
745 : 1, 5, 149, 745
141 : 1, 3, 47, 141
305 : 1, 5, 61, 305
579 : 1, 3, 193, 579
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,745,141,305,579, is 1.
Now, the common factors can be found like this.
991:991
745:5x 149
141:3x 47
305:5x 61
579:3x 193
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5 = 15
Therefore, the value for common factors is 15.
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 = 18383467979025/(1x15)
LCM = 18383467979025/15
LCM = 1225564531935
Thus, we can understand that the LCM of 991,745,141,305,579 is 1225564531935.
