Given numbers are 531,993,393,390,351
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 531,993,393,390,351 is 8979629490.
Find LCM of 531,993,393,390,351 with Prime Factorization
| 3 | 531, 993, 393, 390, 351 |
| 3 | 177, 331, 131, 130, 117 |
| 13 | 59, 331, 131, 130, 39 |
| 59, 331, 131, 10, 3 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 13 x 59 x 331 x 131 x 10 x 3 = 8979629490
Therefore, the lowest common multiple of 531,993,393,390,351 is 8979629490.
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.
531 x 993 x 393 x 390 x 351 = 28366649558910
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.
531 : 1, 3, 9, 59, 177, 531
993 : 1, 3, 331, 993
393 : 1, 3, 131, 393
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
351 : 1, 3, 9, 13, 27, 39, 117, 351
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 531,993,393,390,351, is 3.
Now, the common factors can be found like this.
531:3x 3x 59
993:3x 331
393:3x 131
390:2x 3x 5x 13
351:3x 3x 3x 13
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 13 = 1053
Therefore, the value for common factors is 1053.
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 = 28366649558910/(3x1053)
LCM = 28366649558910/3159
LCM = 8979629490
Thus, we can understand that the LCM of 531,993,393,390,351 is 8979629490.
