Given numbers are 973,489,978,898
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 973,489,978,898 is 427265706.
Find LCM of 973,489,978,898 with Prime Factorization
| 2 | 973, 489, 978, 898 |
| 3 | 973, 489, 489, 449 |
| 163 | 973, 163, 163, 449 |
| 973, 1, 1, 449 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 163 x 973 x 1 x 1 x 449 = 427265706
Therefore, the lowest common multiple of 973,489,978,898 is 427265706.
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.
973 x 489 x 978 x 898 = 417865860468
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.
973 : 1, 7, 139, 973
489 : 1, 3, 163, 489
978 : 1, 2, 3, 6, 163, 326, 489, 978
898 : 1, 2, 449, 898
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 973,489,978,898, is 1.
Now, the common factors can be found like this.
973:7x 139
489:3x 163
978:2x 3x 163
898:2x 449
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 = 417865860468/(1x978)
LCM = 417865860468/978
LCM = 427265706
Thus, we can understand that the LCM of 973,489,978,898 is 427265706.
