Given numbers are 981,537,789,573
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 981,537,789,573 is 8820864567.
Find LCM of 981,537,789,573 with Prime Factorization
| 3 | 981, 537, 789, 573 |
| 327, 179, 263, 191 |
Multiply the prime numbers at the bottom and the left side.
3 x 327 x 179 x 263 x 191 = 8820864567
Therefore, the lowest common multiple of 981,537,789,573 is 8820864567.
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 537 x 789 x 573 = 238163343309
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
537 : 1, 3, 179, 537
789 : 1, 3, 263, 789
573 : 1, 3, 191, 573
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,537,789,573, is 3.
Now, the common factors can be found like this.
981:3x 3x 109
537:3x 179
789:3x 263
573:3x 191
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 238163343309/(3x9)
LCM = 238163343309/27
LCM = 8820864567
Thus, we can understand that the LCM of 981,537,789,573 is 8820864567.
