Given numbers are 217,645,309,835
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 217,645,309,835 is 2407537965.
Find LCM of 217,645,309,835 with Prime Factorization
| 3 | 217, 645, 309, 835 |
| 5 | 217, 215, 103, 835 |
| 217, 43, 103, 167 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 217 x 43 x 103 x 167 = 2407537965
Therefore, the lowest common multiple of 217,645,309,835 is 2407537965.
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 645 x 309 x 835 = 36113069475
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
645 : 1, 3, 5, 15, 43, 129, 215, 645
309 : 1, 3, 103, 309
835 : 1, 5, 167, 835
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 217,645,309,835, is 1.
Now, the common factors can be found like this.
217:7x 31
645:3x 5x 43
309:3x 103
835:5x 167
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5 = 15
Therefore, the value for common factors is 15.
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 = 36113069475/(1x15)
LCM = 36113069475/15
LCM = 2407537965
Thus, we can understand that the LCM of 217,645,309,835 is 2407537965.
