Given numbers are 984,649,687,649,209
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 984,649,687,649,209 is 2778618216.
Find LCM of 984,649,687,649,209 with Prime Factorization
| 3 | 984, 649, 687, 649, 209 |
| 11 | 328, 649, 229, 649, 209 |
| 59 | 328, 59, 229, 59, 19 |
| 328, 1, 229, 1, 19 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 59 x 328 x 1 x 229 x 1 x 19 = 2778618216
Therefore, the lowest common multiple of 984,649,687,649,209 is 2778618216.
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.
984 x 649 x 687 x 649 x 209 = 59509666332072
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.
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
649 : 1, 11, 59, 649
687 : 1, 3, 229, 687
649 : 1, 11, 59, 649
209 : 1, 11, 19, 209
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 984,649,687,649,209, is 1.
Now, the common factors can be found like this.
984:2x 2x 2x 3x 41
649:11x 59
687:3x 229
649:11x 59
209:11x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 11x 59 = 21417
Therefore, the value for common factors is 21417.
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 = 59509666332072/(1x21417)
LCM = 59509666332072/21417
LCM = 2778618216
Thus, we can understand that the LCM of 984,649,687,649,209 is 2778618216.
