Given numbers are 802,476,442,811
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 802,476,442,811 is 2012405668.
Find LCM of 802,476,442,811 with Prime Factorization
| 2 | 802, 476, 442, 811 |
| 17 | 401, 238, 221, 811 |
| 401, 14, 13, 811 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 401 x 14 x 13 x 811 = 2012405668
Therefore, the lowest common multiple of 802,476,442,811 is 2012405668.
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.
802 x 476 x 442 x 811 = 136843585424
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.
802 : 1, 2, 401, 802
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
442 : 1, 2, 13, 17, 26, 34, 221, 442
811 : 1, 811
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 802,476,442,811, is 1.
Now, the common factors can be found like this.
802:2x 401
476:2x 2x 7x 17
442:2x 13x 17
811:811
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 17 = 68
Therefore, the value for common factors is 68.
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 = 136843585424/(1x68)
LCM = 136843585424/68
LCM = 2012405668
Thus, we can understand that the LCM of 802,476,442,811 is 2012405668.
