Given numbers are 989,407,801,129
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 989,407,801,129 is 322420923.
Find LCM of 989,407,801,129 with Prime Factorization
| 3 | 989, 407, 801, 129 |
| 43 | 989, 407, 267, 43 |
| 23, 407, 267, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 43 x 23 x 407 x 267 x 1 = 322420923
Therefore, the lowest common multiple of 989,407,801,129 is 322420923.
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.
989 x 407 x 801 x 129 = 41592299067
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.
989 : 1, 23, 43, 989
407 : 1, 11, 37, 407
801 : 1, 3, 9, 89, 267, 801
129 : 1, 3, 43, 129
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,407,801,129, is 1.
Now, the common factors can be found like this.
989:23x 43
407:11x 37
801:3x 3x 89
129:3x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 43 = 129
Therefore, the value for common factors is 129.
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 = 41592299067/(1x129)
LCM = 41592299067/129
LCM = 322420923
Thus, we can understand that the LCM of 989,407,801,129 is 322420923.
