Given numbers are 978,999,444,842
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 978,999,444,842 is 274217508.
Find LCM of 978,999,444,842 with Prime Factorization
| 2 | 978, 999, 444, 842 |
| 3 | 489, 999, 222, 421 |
| 37 | 163, 333, 74, 421 |
| 163, 9, 2, 421 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 37 x 163 x 9 x 2 x 421 = 274217508
Therefore, the lowest common multiple of 978,999,444,842 is 274217508.
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.
978 x 999 x 444 x 842 = 365257720656
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.
978 : 1, 2, 3, 6, 163, 326, 489, 978
999 : 1, 3, 9, 27, 37, 111, 333, 999
444 : 1, 2, 3, 4, 6, 12, 37, 74, 111, 148, 222, 444
842 : 1, 2, 421, 842
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,999,444,842, is 1.
Now, the common factors can be found like this.
978:2x 3x 163
999:3x 3x 3x 37
444:2x 2x 3x 37
842:2x 421
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3x 37 = 1332
Therefore, the value for common factors is 1332.
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 = 365257720656/(1x1332)
LCM = 365257720656/1332
LCM = 274217508
Thus, we can understand that the LCM of 978,999,444,842 is 274217508.
