Given numbers are 100,103,988,391,845
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 100,103,988,391,845 is 12931660300.
Find LCM of 100,103,988,391,845 with Prime Factorization
| 2 | 100, 103, 988, 391, 845 |
| 2 | 50, 103, 494, 391, 845 |
| 5 | 25, 103, 247, 391, 845 |
| 13 | 5, 103, 247, 391, 169 |
| 5, 103, 19, 391, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 13 x 5 x 103 x 19 x 391 x 13 = 12931660300
Therefore, the lowest common multiple of 100,103,988,391,845 is 12931660300.
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.
100 x 103 x 988 x 391 x 845 = 3362231678000
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.
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
103 : 1, 103
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
391 : 1, 17, 23, 391
845 : 1, 5, 13, 65, 169, 845
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 100,103,988,391,845, is 1.
Now, the common factors can be found like this.
100:2x 2x 5x 5
103:103
988:2x 2x 13x 19
391:17x 23
845:5x 13x 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 2x 5x 13 = 260
Therefore, the value for common factors is 260.
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 = 3362231678000/(1x260)
LCM = 3362231678000/260
LCM = 12931660300
Thus, we can understand that the LCM of 100,103,988,391,845 is 12931660300.
