The LCM of 882,391,568,805 is 489704040.
Find LCM of 882,391,568,805 with Prime Factorization
2 | 882, 391, 568, 805 |
7 | 441, 391, 284, 805 |
23 | 63, 391, 284, 115 |
63, 17, 284, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 23 x 63 x 17 x 284 x 5 = 489704040
Therefore, the lowest common multiple of 882,391,568,805 is 489704040.
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.
882 x 391 x 568 x 805 = 157684700880
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.
882 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 49, 63, 98, 126, 147, 294, 441, 882
391 : 1, 17, 23, 391
568 : 1, 2, 4, 8, 71, 142, 284, 568
805 : 1, 5, 7, 23, 35, 115, 161, 805
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 882,391,568,805, is 1.
Now, the common factors can be found like this.
882:2x 3x 3x 7x 7
391:17x 23
568:2x 2x 2x 71
805:5x 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 7x 23 = 322
Therefore, the value for common factors is 322.
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 = 157684700880/(1x322)
LCM = 157684700880/322
LCM = 489704040
Thus, we can understand that the LCM of 882,391,568,805 is 489704040.
