Given numbers are 803,561,557,917,792
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 803,561,557,917,792 is 502020548568.
Find LCM of 803,561,557,917,792 with Prime Factorization
| 3 | 803, 561, 557, 917, 792 |
| 11 | 803, 187, 557, 917, 264 |
| 73, 17, 557, 917, 24 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 73 x 17 x 557 x 917 x 24 = 502020548568
Therefore, the lowest common multiple of 803,561,557,917,792 is 502020548568.
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.
803 x 561 x 557 x 917 x 792 = 182233459130184
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.
803 : 1, 11, 73, 803
561 : 1, 3, 11, 17, 33, 51, 187, 561
557 : 1, 557
917 : 1, 7, 131, 917
792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 803,561,557,917,792, is 1.
Now, the common factors can be found like this.
803:11x 73
561:3x 11x 17
557:557
917:7x 131
792:2x 2x 2x 3x 3x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 11 = 363
Therefore, the value for common factors is 363.
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 = 182233459130184/(1x363)
LCM = 182233459130184/363
LCM = 502020548568
Thus, we can understand that the LCM of 803,561,557,917,792 is 502020548568.
