Given numbers are 867,646,691,140,460
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 867,646,691,140,460 is 36652754460.
Find LCM of 867,646,691,140,460 with Prime Factorization
| 2 | 867, 646, 691, 140, 460 |
| 2 | 867, 323, 691, 70, 230 |
| 5 | 867, 323, 691, 35, 115 |
| 17 | 867, 323, 691, 7, 23 |
| 51, 19, 691, 7, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 17 x 51 x 19 x 691 x 7 x 23 = 36652754460
Therefore, the lowest common multiple of 867,646,691,140,460 is 36652754460.
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.
867 x 646 x 691 x 140 x 460 = 24923873032800
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.
867 : 1, 3, 17, 51, 289, 867
646 : 1, 2, 17, 19, 34, 38, 323, 646
691 : 1, 691
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 867,646,691,140,460, is 1.
Now, the common factors can be found like this.
867:3x 17x 17
646:2x 17x 19
691:691
140:2x 2x 5x 7
460:2x 2x 5x 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 2x 2x 5x 17 = 680
Therefore, the value for common factors is 680.
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 = 24923873032800/(1x680)
LCM = 24923873032800/680
LCM = 36652754460
Thus, we can understand that the LCM of 867,646,691,140,460 is 36652754460.
