Given numbers are 978,582,172,811
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 978,582,172,811 is 6616524036.
Find LCM of 978,582,172,811 with Prime Factorization
| 2 | 978, 582, 172, 811 |
| 3 | 489, 291, 86, 811 |
| 163, 97, 86, 811 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 163 x 97 x 86 x 811 = 6616524036
Therefore, the lowest common multiple of 978,582,172,811 is 6616524036.
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 582 x 172 x 811 = 79398288432
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
582 : 1, 2, 3, 6, 97, 194, 291, 582
172 : 1, 2, 4, 43, 86, 172
811 : 1, 811
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,582,172,811, is 1.
Now, the common factors can be found like this.
978:2x 3x 163
582:2x 3x 97
172:2x 2x 43
811:811
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 3 = 12
Therefore, the value for common factors is 12.
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 = 79398288432/(1x12)
LCM = 79398288432/12
LCM = 6616524036
Thus, we can understand that the LCM of 978,582,172,811 is 6616524036.
