Given numbers are 820,801,477,514
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 820,801,477,514 is 8946545220.
Find LCM of 820,801,477,514 with Prime Factorization
| 2 | 820, 801, 477, 514 |
| 3 | 410, 801, 477, 257 |
| 3 | 410, 267, 159, 257 |
| 410, 89, 53, 257 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 410 x 89 x 53 x 257 = 8946545220
Therefore, the lowest common multiple of 820,801,477,514 is 8946545220.
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 801 x 477 x 514 = 161037813960
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
801 : 1, 3, 9, 89, 267, 801
477 : 1, 3, 9, 53, 159, 477
514 : 1, 2, 257, 514
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 820,801,477,514, is 1.
Now, the common factors can be found like this.
820:2x 2x 5x 41
801:3x 3x 89
477:3x 3x 53
514:2x 257
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3 = 18
Therefore, the value for common factors is 18.
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 = 161037813960/(1x18)
LCM = 161037813960/18
LCM = 8946545220
Thus, we can understand that the LCM of 820,801,477,514 is 8946545220.
