Find LCM of 805,315,794,330,644 with Prime Factorization
| 2 | 805, 315, 794, 330, 644 |
| 3 | 805, 315, 397, 165, 322 |
| 5 | 805, 105, 397, 55, 322 |
| 7 | 161, 21, 397, 11, 322 |
| 23 | 23, 3, 397, 11, 46 |
| 1, 3, 397, 11, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 23 x 1 x 3 x 397 x 11 x 2 = 126555660
Therefore, the lowest common multiple of 805,315,794,330,644 is 126555660.
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.
805 x 315 x 794 x 330 x 644 = 42788468646000
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.
805 : 1, 5, 7, 23, 35, 115, 161, 805
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
794 : 1, 2, 397, 794
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 805,315,794,330,644, is 1.
Now, the common factors can be found like this.
805:5x 7x 23
315:3x 3x 5x 7
794:2x 397
330:2x 3x 5x 11
644:2x 2x 7x 23
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 3x 5x 5x 7x 7x 23 = 338100
Therefore, the value for common factors is 338100.
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 = 42788468646000/(1x338100)
LCM = 42788468646000/338100
LCM = 126555660
Thus, we can understand that the LCM of 805,315,794,330,644 is 126555660.
