Given numbers are 978,326,811,629
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 978,326,811,629 is 498896382.
Find LCM of 978,326,811,629 with Prime Factorization
| 2 | 978, 326, 811, 629 |
| 163 | 489, 163, 811, 629 |
| 3, 1, 811, 629 |
Multiply the prime numbers at the bottom and the left side.
2 x 163 x 3 x 1 x 811 x 629 = 498896382
Therefore, the lowest common multiple of 978,326,811,629 is 498896382.
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 326 x 811 x 629 = 162640220532
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
326 : 1, 2, 163, 326
811 : 1, 811
629 : 1, 17, 37, 629
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,326,811,629, is 1.
Now, the common factors can be found like this.
978:2x 3x 163
326:2x 163
811:811
629:17x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 163 = 326
Therefore, the value for common factors is 326.
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 = 162640220532/(1x326)
LCM = 162640220532/326
LCM = 498896382
Thus, we can understand that the LCM of 978,326,811,629 is 498896382.
