Given numbers are 987,694,913,363,789
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 987,694,913,363,789 is 1809238556202.
Find LCM of 987,694,913,363,789 with Prime Factorization
| 3 | 987, 694, 913, 363, 789 |
| 11 | 329, 694, 913, 121, 263 |
| 329, 694, 83, 11, 263 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 329 x 694 x 83 x 11 x 263 = 1809238556202
Therefore, the lowest common multiple of 987,694,913,363,789 is 1809238556202.
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.
987 x 694 x 913 x 363 x 789 = 179114617063998
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.
987 : 1, 3, 7, 21, 47, 141, 329, 987
694 : 1, 2, 347, 694
913 : 1, 11, 83, 913
363 : 1, 3, 11, 33, 121, 363
789 : 1, 3, 263, 789
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,694,913,363,789, is 1.
Now, the common factors can be found like this.
987:3x 7x 47
694:2x 347
913:11x 83
363:3x 11x 11
789:3x 263
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 11 = 99
Therefore, the value for common factors is 99.
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 = 179114617063998/(1x99)
LCM = 179114617063998/99
LCM = 1809238556202
Thus, we can understand that the LCM of 987,694,913,363,789 is 1809238556202.
