Find LCM of 775,891,868,684,451 with Prime Factorization
| 2 | 775, 891, 868, 684, 451 |
| 2 | 775, 891, 434, 342, 451 |
| 3 | 775, 891, 217, 171, 451 |
| 3 | 775, 297, 217, 57, 451 |
| 11 | 775, 99, 217, 19, 451 |
| 31 | 775, 9, 217, 19, 41 |
| 25, 9, 7, 19, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 11 x 31 x 25 x 9 x 7 x 19 x 41 = 15061731300
Therefore, the lowest common multiple of 775,891,868,684,451 is 15061731300.
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.
775 x 891 x 868 x 684 x 451 = 184897813438800
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.
775 : 1, 5, 25, 31, 155, 775
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
451 : 1, 11, 41, 451
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 775,891,868,684,451, is 1.
Now, the common factors can be found like this.
775:5x 5x 31
891:3x 3x 3x 3x 11
868:2x 2x 7x 31
684:2x 2x 3x 3x 19
451:11x 41
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 3x 3x 11x 31 = 12276
Therefore, the value for common factors is 12276.
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 = 184897813438800/(1x12276)
LCM = 184897813438800/12276
LCM = 15061731300
Thus, we can understand that the LCM of 775,891,868,684,451 is 15061731300.
