Given numbers are 981,217,520,933,754
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 981,217,520,933,754 is 998367584760.
Find LCM of 981,217,520,933,754 with Prime Factorization
| 2 | 981, 217, 520, 933, 754 |
| 3 | 981, 217, 260, 933, 377 |
| 13 | 327, 217, 260, 311, 377 |
| 327, 217, 20, 311, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 327 x 217 x 20 x 311 x 29 = 998367584760
Therefore, the lowest common multiple of 981,217,520,933,754 is 998367584760.
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 217 x 520 x 933 x 754 = 77872671611280
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
217 : 1, 7, 31, 217
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
933 : 1, 3, 311, 933
754 : 1, 2, 13, 26, 29, 58, 377, 754
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,217,520,933,754, is 1.
Now, the common factors can be found like this.
981:3x 3x 109
217:7x 31
520:2x 2x 2x 5x 13
933:3x 311
754:2x 13x 29
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 13 = 78
Therefore, the value for common factors is 78.
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 = 77872671611280/(1x78)
LCM = 77872671611280/78
LCM = 998367584760
Thus, we can understand that the LCM of 981,217,520,933,754 is 998367584760.
