Given numbers are 161,715,682,671,196
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 161,715,682,671,196 is 6095109020.
Find LCM of 161,715,682,671,196 with Prime Factorization
| 2 | 161, 715, 682, 671, 196 |
| 7 | 161, 715, 341, 671, 98 |
| 11 | 23, 715, 341, 671, 14 |
| 23, 65, 31, 61, 14 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 11 x 23 x 65 x 31 x 61 x 14 = 6095109020
Therefore, the lowest common multiple of 161,715,682,671,196 is 6095109020.
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.
161 x 715 x 682 x 671 x 196 = 10325114679880
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.
161 : 1, 7, 23, 161
715 : 1, 5, 11, 13, 55, 65, 143, 715
682 : 1, 2, 11, 22, 31, 62, 341, 682
671 : 1, 11, 61, 671
196 : 1, 2, 4, 7, 14, 28, 49, 98, 196
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,715,682,671,196, is 1.
Now, the common factors can be found like this.
161:7x 23
715:5x 11x 13
682:2x 11x 31
671:11x 61
196:2x 2x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 11x 11 = 1694
Therefore, the value for common factors is 1694.
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 = 10325114679880/(1x1694)
LCM = 10325114679880/1694
LCM = 6095109020
Thus, we can understand that the LCM of 161,715,682,671,196 is 6095109020.
