Given numbers are 987,217,327,841
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 987,217,327,841 is 2804796393.
Find LCM of 987,217,327,841 with Prime Factorization
| 3 | 987, 217, 327, 841 |
| 7 | 329, 217, 109, 841 |
| 47, 31, 109, 841 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 47 x 31 x 109 x 841 = 2804796393
Therefore, the lowest common multiple of 987,217,327,841 is 2804796393.
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 217 x 327 x 841 = 58900724253
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
217 : 1, 7, 31, 217
327 : 1, 3, 109, 327
841 : 1, 29, 841
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,217,327,841, is 1.
Now, the common factors can be found like this.
987:3x 7x 47
217:7x 31
327:3x 109
841:29x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7 = 21
Therefore, the value for common factors is 21.
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 = 58900724253/(1x21)
LCM = 58900724253/21
LCM = 2804796393
Thus, we can understand that the LCM of 987,217,327,841 is 2804796393.
