Given numbers are 217,491,126,903,311
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 217,491,126,903,311 is 25647354558.
Find LCM of 217,491,126,903,311 with Prime Factorization
| 3 | 217, 491, 126, 903, 311 |
| 7 | 217, 491, 42, 301, 311 |
| 31, 491, 6, 43, 311 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 31 x 491 x 6 x 43 x 311 = 25647354558
Therefore, the lowest common multiple of 217,491,126,903,311 is 25647354558.
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.
217 x 491 x 126 x 903 x 311 = 3770161120026
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.
217 : 1, 7, 31, 217
491 : 1, 491
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
903 : 1, 3, 7, 21, 43, 129, 301, 903
311 : 1, 311
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 217,491,126,903,311, is 1.
Now, the common factors can be found like this.
217:7x 31
491:491
126:2x 3x 3x 7
903:3x 7x 43
311:311
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 7 = 147
Therefore, the value for common factors is 147.
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 = 3770161120026/(1x147)
LCM = 3770161120026/147
LCM = 25647354558
Thus, we can understand that the LCM of 217,491,126,903,311 is 25647354558.
