The LCM of 805,297,859,644,782 is 13965433020.
Find LCM of 805,297,859,644,782 with Prime Factorization
| 2 | 805, 297, 859, 644, 782 |
| 7 | 805, 297, 859, 322, 391 |
| 23 | 115, 297, 859, 46, 391 |
| 5, 297, 859, 2, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 23 x 5 x 297 x 859 x 2 x 17 = 13965433020
Therefore, the lowest common multiple of 805,297,859,644,782 is 13965433020.
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 297 x 859 x 644 x 782 = 103427996946120
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
297 : 1, 3, 9, 11, 27, 33, 99, 297
859 : 1, 859
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
782 : 1, 2, 17, 23, 34, 46, 391, 782
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 805,297,859,644,782, is 1.
Now, the common factors can be found like this.
805:5x 7x 23
297:3x 3x 3x 11
859:859
644:2x 2x 7x 23
782:2x 17x 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 23x 23 = 7406
Therefore, the value for common factors is 7406.
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 = 103427996946120/(1x7406)
LCM = 103427996946120/7406
LCM = 13965433020
Thus, we can understand that the LCM of 805,297,859,644,782 is 13965433020.
