Find LCM of 663,806,878,945,691 with Prime Factorization
2 | 663, 806, 878, 945, 691 |
3 | 663, 403, 439, 945, 691 |
13 | 221, 403, 439, 315, 691 |
17, 31, 439, 315, 691 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 17 x 31 x 439 x 315 x 691 = 3927881158110
Therefore, the lowest common multiple of 663,806,878,945,691 is 3927881158110.
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 806 x 878 x 945 x 691 = 306374730332580
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
806 : 1, 2, 13, 26, 31, 62, 403, 806
878 : 1, 2, 439, 878
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
691 : 1, 691
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 663,806,878,945,691, is 1.
Now, the common factors can be found like this.
663:3x 13x 17
806:2x 13x 31
878:2x 439
945:3x 3x 3x 5x 7
691:691
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 13 = 78
Therefore, the value for common factors is 78.
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 = 306374730332580/(1x78)
LCM = 306374730332580/78
LCM = 3927881158110
Thus, we can understand that the LCM of 663,806,878,945,691 is 3927881158110.
