Given numbers are 981,838,819,711,939
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 981,838,819,711,939 is 1849804566246.
Find LCM of 981,838,819,711,939 with Prime Factorization
3 | 981, 838, 819, 711, 939 |
3 | 327, 838, 273, 237, 313 |
109, 838, 91, 79, 313 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 109 x 838 x 91 x 79 x 313 = 1849804566246
Therefore, the lowest common multiple of 981,838,819,711,939 is 1849804566246.
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.
981 x 838 x 819 x 711 x 939 = 449502509597778
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.
981 : 1, 3, 9, 109, 327, 981
838 : 1, 2, 419, 838
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
711 : 1, 3, 9, 79, 237, 711
939 : 1, 3, 313, 939
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,838,819,711,939, is 1.
Now, the common factors can be found like this.
981:3x 3x 109
838:2x 419
819:3x 3x 7x 13
711:3x 3x 79
939:3x 313
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 3 = 243
Therefore, the value for common factors is 243.
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 = 449502509597778/(1x243)
LCM = 449502509597778/243
LCM = 1849804566246
Thus, we can understand that the LCM of 981,838,819,711,939 is 1849804566246.
