Given numbers are 1,489,978,458
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 1,489,978,458 is 223962.
Find LCM of 1,489,978,458 with Prime Factorization
| 2 | 1, 489, 978, 458 |
| 3 | 1, 489, 489, 229 |
| 163 | 1, 163, 163, 229 |
| 1, 1, 1, 229 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 163 x 1 x 1 x 1 x 229 = 223962
Therefore, the lowest common multiple of 1,489,978,458 is 223962.
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.
1 x 489 x 978 x 458 = 219034836
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.
1 : 1
489 : 1, 3, 163, 489
978 : 1, 2, 3, 6, 163, 326, 489, 978
458 : 1, 2, 229, 458
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1,489,978,458, is 1.
Now, the common factors can be found like this.
1:
489:3x 163
978:2x 3x 163
458:2x 229
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 163 = 978
Therefore, the value for common factors is 978.
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 = 219034836/(1x978)
LCM = 219034836/978
LCM = 223962
Thus, we can understand that the LCM of 1,489,978,458 is 223962.
