Given numbers are 198,726,556,902
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 198,726,556,902 is 24824844.
Find LCM of 198,726,556,902 with Prime Factorization
| 2 | 198, 726, 556, 902 |
| 3 | 99, 363, 278, 451 |
| 11 | 33, 121, 278, 451 |
| 3, 11, 278, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 3 x 11 x 278 x 41 = 24824844
Therefore, the lowest common multiple of 198,726,556,902 is 24824844.
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 726 x 556 x 902 = 72091346976
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
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
556 : 1, 2, 4, 139, 278, 556
902 : 1, 2, 11, 22, 41, 82, 451, 902
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 198,726,556,902, is 2.
Now, the common factors can be found like this.
198:2x 3x 3x 11
726:2x 3x 11x 11
556:2x 2x 139
902:2x 11x 41
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 3x 11x 11 = 1452
Therefore, the value for common factors is 1452.
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 = 72091346976/(2x1452)
LCM = 72091346976/2904
LCM = 24824844
Thus, we can understand that the LCM of 198,726,556,902 is 24824844.
