Given numbers are 663,794,820,208,521
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 663,794,820,208,521 is 449796013680.
Find LCM of 663,794,820,208,521 with Prime Factorization
2 | 663, 794, 820, 208, 521 |
2 | 663, 397, 410, 104, 521 |
13 | 663, 397, 205, 52, 521 |
51, 397, 205, 4, 521 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 51 x 397 x 205 x 4 x 521 = 449796013680
Therefore, the lowest common multiple of 663,794,820,208,521 is 449796013680.
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.
663 x 794 x 820 x 208 x 521 = 46778785422720
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.
663 : 1, 3, 13, 17, 39, 51, 221, 663
794 : 1, 2, 397, 794
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
521 : 1, 521
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 663,794,820,208,521, is 1.
Now, the common factors can be found like this.
663:3x 13x 17
794:2x 397
820:2x 2x 5x 41
208:2x 2x 2x 2x 13
521:521
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 13 = 104
Therefore, the value for common factors is 104.
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 = 46778785422720/(1x104)
LCM = 46778785422720/104
LCM = 449796013680
Thus, we can understand that the LCM of 663,794,820,208,521 is 449796013680.
