Given numbers are 798,981,504
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 798,981,504 is 1043784.
Find LCM of 798,981,504 with Prime Factorization
| 2 | 798, 981, 504 |
| 3 | 399, 981, 252 |
| 3 | 133, 327, 84 |
| 7 | 133, 109, 28 |
| 19, 109, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 19 x 109 x 4 = 1043784
Therefore, the lowest common multiple of 798,981,504 is 1043784.
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.
798 x 981 x 504 = 394550352
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.
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
981 : 1, 3, 9, 109, 327, 981
504 : 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, 504
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 798,981,504, is 3.
Now, the common factors can be found like this.
798:2x 3x 7x 19
981:3x 3x 109
504:2x 2x 2x 3x 3x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 7 = 126
Therefore, the value for common factors is 126.
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 = 394550352/(3x126)
LCM = 394550352/378
LCM = 1043784
Thus, we can understand that the LCM of 798,981,504 is 1043784.
