Given numbers are 861,882,465,462,313
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 861,882,465,462,313 is 19298393730.
Find LCM of 861,882,465,462,313 with Prime Factorization
| 2 | 861, 882, 465, 462, 313 |
| 3 | 861, 441, 465, 231, 313 |
| 7 | 287, 147, 155, 77, 313 |
| 41, 21, 155, 11, 313 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 41 x 21 x 155 x 11 x 313 = 19298393730
Therefore, the lowest common multiple of 861,882,465,462,313 is 19298393730.
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.
861 x 882 x 465 x 462 x 313 = 51063549809580
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.
861 : 1, 3, 7, 21, 41, 123, 287, 861
882 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 49, 63, 98, 126, 147, 294, 441, 882
465 : 1, 3, 5, 15, 31, 93, 155, 465
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
313 : 1, 313
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,882,465,462,313, is 1.
Now, the common factors can be found like this.
861:3x 7x 41
882:2x 3x 3x 7x 7
465:3x 5x 31
462:2x 3x 7x 11
313:313
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 7x 7 = 2646
Therefore, the value for common factors is 2646.
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 = 51063549809580/(1x2646)
LCM = 51063549809580/2646
LCM = 19298393730
Thus, we can understand that the LCM of 861,882,465,462,313 is 19298393730.
