Given numbers are 198,455,511,949
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 198,455,511,949 is 6576570.
Find LCM of 198,455,511,949 with Prime Factorization
| 7 | 198, 455, 511, 949 |
| 13 | 198, 65, 73, 949 |
| 73 | 198, 5, 73, 73 |
| 198, 5, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
7 x 13 x 73 x 198 x 5 x 1 x 1 = 6576570
Therefore, the lowest common multiple of 198,455,511,949 is 6576570.
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.
198 x 455 x 511 x 949 = 43688154510
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.
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
455 : 1, 5, 7, 13, 35, 65, 91, 455
511 : 1, 7, 73, 511
949 : 1, 13, 73, 949
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 198,455,511,949, is 1.
Now, the common factors can be found like this.
198:2x 3x 3x 11
455:5x 7x 13
511:7x 73
949:13x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 13x 73 = 6643
Therefore, the value for common factors is 6643.
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 = 43688154510/(1x6643)
LCM = 43688154510/6643
LCM = 6576570
Thus, we can understand that the LCM of 198,455,511,949 is 6576570.
