Given numbers are 186,715,686,966,917
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 186,715,686,966,917 is 137439712410.
Find LCM of 186,715,686,966,917 with Prime Factorization
| 2 | 186, 715, 686, 966, 917 |
| 3 | 93, 715, 343, 483, 917 |
| 7 | 31, 715, 343, 161, 917 |
| 31, 715, 49, 23, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 31 x 715 x 49 x 23 x 131 = 137439712410
Therefore, the lowest common multiple of 186,715,686,966,917 is 137439712410.
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.
186 x 715 x 686 x 966 x 917 = 80814550897080
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.
186 : 1, 2, 3, 6, 31, 62, 93, 186
715 : 1, 5, 11, 13, 55, 65, 143, 715
686 : 1, 2, 7, 14, 49, 98, 343, 686
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
917 : 1, 7, 131, 917
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 186,715,686,966,917, is 1.
Now, the common factors can be found like this.
186:2x 3x 31
715:5x 11x 13
686:2x 7x 7x 7
966:2x 3x 7x 23
917:7x 131
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 7x 7 = 588
Therefore, the value for common factors is 588.
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 = 80814550897080/(1x588)
LCM = 80814550897080/588
LCM = 137439712410
Thus, we can understand that the LCM of 186,715,686,966,917 is 137439712410.
