Given numbers are 981,715,122,408,741
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 981,715,122,408,741 is 110559837960.
Find LCM of 981,715,122,408,741 with Prime Factorization
| 2 | 981, 715, 122, 408, 741 |
| 3 | 981, 715, 61, 204, 741 |
| 13 | 327, 715, 61, 68, 247 |
| 327, 55, 61, 68, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 327 x 55 x 61 x 68 x 19 = 110559837960
Therefore, the lowest common multiple of 981,715,122,408,741 is 110559837960.
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.
981 x 715 x 122 x 408 x 741 = 25871002082640
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.
981 : 1, 3, 9, 109, 327, 981
715 : 1, 5, 11, 13, 55, 65, 143, 715
122 : 1, 2, 61, 122
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
741 : 1, 3, 13, 19, 39, 57, 247, 741
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,715,122,408,741, is 1.
Now, the common factors can be found like this.
981:3x 3x 109
715:5x 11x 13
122:2x 61
408:2x 2x 2x 3x 17
741:3x 13x 19
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 13 = 234
Therefore, the value for common factors is 234.
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 = 25871002082640/(1x234)
LCM = 25871002082640/234
LCM = 110559837960
Thus, we can understand that the LCM of 981,715,122,408,741 is 110559837960.
