Given numbers are 820,410,454,174,395
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 820,410,454,174,395 is 1279340220.
Find LCM of 820,410,454,174,395 with Prime Factorization
| 2 | 820, 410, 454, 174, 395 |
| 5 | 410, 205, 227, 87, 395 |
| 41 | 82, 41, 227, 87, 79 |
| 2, 1, 227, 87, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 41 x 2 x 1 x 227 x 87 x 79 = 1279340220
Therefore, the lowest common multiple of 820,410,454,174,395 is 1279340220.
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.
820 x 410 x 454 x 174 x 395 = 10490589804000
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.
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
410 : 1, 2, 5, 10, 41, 82, 205, 410
454 : 1, 2, 227, 454
174 : 1, 2, 3, 6, 29, 58, 87, 174
395 : 1, 5, 79, 395
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 820,410,454,174,395, is 1.
Now, the common factors can be found like this.
820:2x 2x 5x 41
410:2x 5x 41
454:2x 227
174:2x 3x 29
395:5x 79
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 2x 5x 5x 41 = 8200
Therefore, the value for common factors is 8200.
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 = 10490589804000/(1x8200)
LCM = 10490589804000/8200
LCM = 1279340220
Thus, we can understand that the LCM of 820,410,454,174,395 is 1279340220.
