Given numbers are 408,902,741,993
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 408,902,741,993 is 15043942056.
Find LCM of 408,902,741,993 with Prime Factorization
| 2 | 408, 902, 741, 993 |
| 3 | 204, 451, 741, 993 |
| 68, 451, 247, 331 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 68 x 451 x 247 x 331 = 15043942056
Therefore, the lowest common multiple of 408,902,741,993 is 15043942056.
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.
408 x 902 x 741 x 993 = 270790957008
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.
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
902 : 1, 2, 11, 22, 41, 82, 451, 902
741 : 1, 3, 13, 19, 39, 57, 247, 741
993 : 1, 3, 331, 993
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 408,902,741,993, is 1.
Now, the common factors can be found like this.
408:2x 2x 2x 3x 17
902:2x 11x 41
741:3x 13x 19
993:3x 331
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 3 = 18
Therefore, the value for common factors is 18.
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 = 270790957008/(1x18)
LCM = 270790957008/18
LCM = 15043942056
Thus, we can understand that the LCM of 408,902,741,993 is 15043942056.
