Given numbers are 978,424,804,727
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 978,424,804,727 is 10099129224.
Find LCM of 978,424,804,727 with Prime Factorization
| 2 | 978, 424, 804, 727 |
| 2 | 489, 212, 402, 727 |
| 3 | 489, 106, 201, 727 |
| 163, 106, 67, 727 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 163 x 106 x 67 x 727 = 10099129224
Therefore, the lowest common multiple of 978,424,804,727 is 10099129224.
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 424 x 804 x 727 = 242379101376
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
424 : 1, 2, 4, 8, 53, 106, 212, 424
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
727 : 1, 727
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,424,804,727, is 1.
Now, the common factors can be found like this.
978:2x 3x 163
424:2x 2x 2x 53
804:2x 2x 3x 67
727:727
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 3 = 24
Therefore, the value for common factors is 24.
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 = 242379101376/(1x24)
LCM = 242379101376/24
LCM = 10099129224
Thus, we can understand that the LCM of 978,424,804,727 is 10099129224.
