Given numbers are 989,339,172,812
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 989,339,172,812 is 272240052.
Find LCM of 989,339,172,812 with Prime Factorization
| 2 | 989, 339, 172, 812 |
| 2 | 989, 339, 86, 406 |
| 43 | 989, 339, 43, 203 |
| 23, 339, 1, 203 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 43 x 23 x 339 x 1 x 203 = 272240052
Therefore, the lowest common multiple of 989,339,172,812 is 272240052.
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.
989 x 339 x 172 x 812 = 46825288944
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.
989 : 1, 23, 43, 989
339 : 1, 3, 113, 339
172 : 1, 2, 4, 43, 86, 172
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,339,172,812, is 1.
Now, the common factors can be found like this.
989:23x 43
339:3x 113
172:2x 2x 43
812:2x 2x 7x 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 2x 43 = 172
Therefore, the value for common factors is 172.
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 = 46825288944/(1x172)
LCM = 46825288944/172
LCM = 272240052
Thus, we can understand that the LCM of 989,339,172,812 is 272240052.
