Given numbers are 981,995,117,819,871
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 981,995,117,819,871 is 5951251215.
Find LCM of 981,995,117,819,871 with Prime Factorization
| 3 | 981, 995, 117, 819, 871 |
| 3 | 327, 995, 39, 273, 871 |
| 13 | 109, 995, 13, 91, 871 |
| 109, 995, 1, 7, 67 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 13 x 109 x 995 x 1 x 7 x 67 = 5951251215
Therefore, the lowest common multiple of 981,995,117,819,871 is 5951251215.
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.
981 x 995 x 117 x 819 x 871 = 81466677882135
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.
981 : 1, 3, 9, 109, 327, 981
995 : 1, 5, 199, 995
117 : 1, 3, 9, 13, 39, 117
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
871 : 1, 13, 67, 871
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,995,117,819,871, is 1.
Now, the common factors can be found like this.
981:3x 3x 109
995:5x 199
117:3x 3x 13
819:3x 3x 7x 13
871:13x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 13x 13 = 13689
Therefore, the value for common factors is 13689.
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 = 81466677882135/(1x13689)
LCM = 81466677882135/13689
LCM = 5951251215
Thus, we can understand that the LCM of 981,995,117,819,871 is 5951251215.
