Given numbers are 876,811,630,561,218
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 876,811,630,561,218 is 1520485783740.
Find LCM of 876,811,630,561,218 with Prime Factorization
| 2 | 876, 811, 630, 561, 218 |
| 3 | 438, 811, 315, 561, 109 |
| 146, 811, 105, 187, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 146 x 811 x 105 x 187 x 109 = 1520485783740
Therefore, the lowest common multiple of 876,811,630,561,218 is 1520485783740.
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.
876 x 811 x 630 x 561 x 218 = 54737488214640
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.
876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876
811 : 1, 811
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
561 : 1, 3, 11, 17, 33, 51, 187, 561
218 : 1, 2, 109, 218
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 876,811,630,561,218, is 1.
Now, the common factors can be found like this.
876:2x 2x 3x 73
811:811
630:2x 3x 3x 5x 7
561:3x 11x 17
218:2x 109
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 3 = 36
Therefore, the value for common factors is 36.
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 = 54737488214640/(1x36)
LCM = 54737488214640/36
LCM = 1520485783740
Thus, we can understand that the LCM of 876,811,630,561,218 is 1520485783740.
