Given numbers are 821,741,209,579,361
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 821,741,209,579,361 is 24539457657.
Find LCM of 821,741,209,579,361 with Prime Factorization
| 3 | 821, 741, 209, 579, 361 |
| 19 | 821, 247, 209, 193, 361 |
| 821, 13, 11, 193, 19 |
Multiply the prime numbers at the bottom and the left side.
3 x 19 x 821 x 13 x 11 x 193 x 19 = 24539457657
Therefore, the lowest common multiple of 821,741,209,579,361 is 24539457657.
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.
821 x 741 x 209 x 579 x 361 = 26576232642531
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.
821 : 1, 821
741 : 1, 3, 13, 19, 39, 57, 247, 741
209 : 1, 11, 19, 209
579 : 1, 3, 193, 579
361 : 1, 19, 361
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,741,209,579,361, is 1.
Now, the common factors can be found like this.
821:821
741:3x 13x 19
209:11x 19
579:3x 193
361:19x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 19x 19 = 1083
Therefore, the value for common factors is 1083.
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 = 26576232642531/(1x1083)
LCM = 26576232642531/1083
LCM = 24539457657
Thus, we can understand that the LCM of 821,741,209,579,361 is 24539457657.
