Given numbers are 547,917,978,489
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 547,917,978,489 is 490563822.
Find LCM of 547,917,978,489 with Prime Factorization
| 3 | 547, 917, 978, 489 |
| 163 | 547, 917, 326, 163 |
| 547, 917, 2, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 163 x 547 x 917 x 2 x 1 = 490563822
Therefore, the lowest common multiple of 547,917,978,489 is 490563822.
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.
547 x 917 x 978 x 489 = 239885708958
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.
547 : 1, 547
917 : 1, 7, 131, 917
978 : 1, 2, 3, 6, 163, 326, 489, 978
489 : 1, 3, 163, 489
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 547,917,978,489, is 1.
Now, the common factors can be found like this.
547:547
917:7x 131
978:2x 3x 163
489:3x 163
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 163 = 489
Therefore, the value for common factors is 489.
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 = 239885708958/(1x489)
LCM = 239885708958/489
LCM = 490563822
Thus, we can understand that the LCM of 547,917,978,489 is 490563822.
