Given numbers are 646,894,511,149
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 646,894,511,149 is 147557382.
Find LCM of 646,894,511,149 with Prime Factorization
| 2 | 646, 894, 511, 149 |
| 149 | 323, 447, 511, 149 |
| 323, 3, 511, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 149 x 323 x 3 x 511 x 1 = 147557382
Therefore, the lowest common multiple of 646,894,511,149 is 147557382.
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.
646 x 894 x 511 x 149 = 43972099836
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.
646 : 1, 2, 17, 19, 34, 38, 323, 646
894 : 1, 2, 3, 6, 149, 298, 447, 894
511 : 1, 7, 73, 511
149 : 1, 149
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,894,511,149, is 1.
Now, the common factors can be found like this.
646:2x 17x 19
894:2x 3x 149
511:7x 73
149:149
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 149 = 298
Therefore, the value for common factors is 298.
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 = 43972099836/(1x298)
LCM = 43972099836/298
LCM = 147557382
Thus, we can understand that the LCM of 646,894,511,149 is 147557382.
