Given numbers are 821,522,821,493
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 821,522,821,493 is 7285554.
Find LCM of 821,522,821,493 with Prime Factorization
| 29 | 821, 522, 821, 493 |
| 821 | 821, 18, 821, 17 |
| 1, 18, 1, 17 |
Multiply the prime numbers at the bottom and the left side.
29 x 821 x 1 x 18 x 1 x 17 = 7285554
Therefore, the lowest common multiple of 821,522,821,493 is 7285554.
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 522 x 821 x 493 = 173461755186
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
522 : 1, 2, 3, 6, 9, 18, 29, 58, 87, 174, 261, 522
821 : 1, 821
493 : 1, 17, 29, 493
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,522,821,493, is 1.
Now, the common factors can be found like this.
821:821
522:2x 3x 3x 29
821:821
493:17x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
29x 821 = 23809
Therefore, the value for common factors is 23809.
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 = 173461755186/(1x23809)
LCM = 173461755186/23809
LCM = 7285554
Thus, we can understand that the LCM of 821,522,821,493 is 7285554.
