Given numbers are 988,451,703,331
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 988,451,703,331 is 5457116236.
Find LCM of 988,451,703,331 with Prime Factorization
| 19 | 988, 451, 703, 331 |
| 52, 451, 37, 331 |
Multiply the prime numbers at the bottom and the left side.
19 x 52 x 451 x 37 x 331 = 5457116236
Therefore, the lowest common multiple of 988,451,703,331 is 5457116236.
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.
988 x 451 x 703 x 331 = 103685208484
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.
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
451 : 1, 11, 41, 451
703 : 1, 19, 37, 703
331 : 1, 331
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 988,451,703,331, is 1.
Now, the common factors can be found like this.
988:2x 2x 13x 19
451:11x 41
703:19x 37
331:331
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19 = 19
Therefore, the value for common factors is 19.
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 = 103685208484/(1x19)
LCM = 103685208484/19
LCM = 5457116236
Thus, we can understand that the LCM of 988,451,703,331 is 5457116236.
