Given numbers are 806,802,746,756,280
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 806,802,746,756,280 is 455701067640.
Find LCM of 806,802,746,756,280 with Prime Factorization
| 2 | 806, 802, 746, 756, 280 |
| 2 | 403, 401, 373, 378, 140 |
| 7 | 403, 401, 373, 189, 70 |
| 403, 401, 373, 27, 10 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 403 x 401 x 373 x 27 x 10 = 455701067640
Therefore, the lowest common multiple of 806,802,746,756,280 is 455701067640.
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.
806 x 802 x 746 x 756 x 280 = 102077039151360
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.
806 : 1, 2, 13, 26, 31, 62, 403, 806
802 : 1, 2, 401, 802
746 : 1, 2, 373, 746
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 806,802,746,756,280, is 2.
Now, the common factors can be found like this.
806:2x 13x 31
802:2x 401
746:2x 373
756:2x 2x 3x 3x 3x 7
280:2x 2x 2x 5x 7
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 2x 7 = 112
Therefore, the value for common factors is 112.
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 = 102077039151360/(2x112)
LCM = 102077039151360/224
LCM = 455701067640
Thus, we can understand that the LCM of 806,802,746,756,280 is 455701067640.
