Given numbers are 819,562,876,754
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 819,562,876,754 is 1948817052.
Find LCM of 819,562,876,754 with Prime Factorization
| 2 | 819, 562, 876, 754 |
| 3 | 819, 281, 438, 377 |
| 13 | 273, 281, 146, 377 |
| 21, 281, 146, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 21 x 281 x 146 x 29 = 1948817052
Therefore, the lowest common multiple of 819,562,876,754 is 1948817052.
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.
819 x 562 x 876 x 754 = 304015460112
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.
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
562 : 1, 2, 281, 562
876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876
754 : 1, 2, 13, 26, 29, 58, 377, 754
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 819,562,876,754, is 1.
Now, the common factors can be found like this.
819:3x 3x 7x 13
562:2x 281
876:2x 2x 3x 73
754:2x 13x 29
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 13 = 156
Therefore, the value for common factors is 156.
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 = 304015460112/(1x156)
LCM = 304015460112/156
LCM = 1948817052
Thus, we can understand that the LCM of 819,562,876,754 is 1948817052.
