Given numbers are 820,819,927,793
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 820,819,927,793 is 4219537140.
Find LCM of 820,819,927,793 with Prime Factorization
3 | 820, 819, 927, 793 |
3 | 820, 273, 309, 793 |
13 | 820, 91, 103, 793 |
820, 7, 103, 61 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 13 x 820 x 7 x 103 x 61 = 4219537140
Therefore, the lowest common multiple of 820,819,927,793 is 4219537140.
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.
820 x 819 x 927 x 793 = 493685845380
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.
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
927 : 1, 3, 9, 103, 309, 927
793 : 1, 13, 61, 793
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 820,819,927,793, is 1.
Now, the common factors can be found like this.
820:2x 2x 5x 41
819:3x 3x 7x 13
927:3x 3x 103
793:13x 61
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 13 = 117
Therefore, the value for common factors is 117.
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 = 493685845380/(1x117)
LCM = 493685845380/117
LCM = 4219537140
Thus, we can understand that the LCM of 820,819,927,793 is 4219537140.
