Given numbers are 978,190,364,494,238
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 978,190,364,494,238 is 287463540.
Find LCM of 978,190,364,494,238 with Prime Factorization
| 2 | 978, 190, 364, 494, 238 |
| 7 | 489, 95, 182, 247, 119 |
| 13 | 489, 95, 26, 247, 17 |
| 19 | 489, 95, 2, 19, 17 |
| 489, 5, 2, 1, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 13 x 19 x 489 x 5 x 2 x 1 x 17 = 287463540
Therefore, the lowest common multiple of 978,190,364,494,238 is 287463540.
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 190 x 364 x 494 x 238 = 7952391370560
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
190 : 1, 2, 5, 10, 19, 38, 95, 190
364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364
494 : 1, 2, 13, 19, 26, 38, 247, 494
238 : 1, 2, 7, 14, 17, 34, 119, 238
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,190,364,494,238, is 2.
Now, the common factors can be found like this.
978:2x 3x 163
190:2x 5x 19
364:2x 2x 7x 13
494:2x 13x 19
238:2x 7x 17
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 2x 7x 13x 19 = 13832
Therefore, the value for common factors is 13832.
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 = 7952391370560/(2x13832)
LCM = 7952391370560/27664
LCM = 287463540
Thus, we can understand that the LCM of 978,190,364,494,238 is 287463540.
