Given numbers are 209,738,798,876
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 209,738,798,876 is 157635324.
Find LCM of 209,738,798,876 with Prime Factorization
| 2 | 209, 738, 798, 876 |
| 3 | 209, 369, 399, 438 |
| 19 | 209, 123, 133, 146 |
| 11, 123, 7, 146 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 11 x 123 x 7 x 146 = 157635324
Therefore, the lowest common multiple of 209,738,798,876 is 157635324.
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.
209 x 738 x 798 x 876 = 107822561616
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.
209 : 1, 11, 19, 209
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 209,738,798,876, is 1.
Now, the common factors can be found like this.
209:11x 19
738:2x 3x 3x 41
798:2x 3x 7x 19
876:2x 2x 3x 73
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 3x 19 = 684
Therefore, the value for common factors is 684.
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 = 107822561616/(1x684)
LCM = 107822561616/684
LCM = 157635324
Thus, we can understand that the LCM of 209,738,798,876 is 157635324.
