Find LCM of 812,969,646,486 with Prime Factorization
2 | 812, 969, 646, 486 |
3 | 406, 969, 323, 243 |
17 | 406, 323, 323, 81 |
19 | 406, 19, 19, 81 |
406, 1, 1, 81 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 19 x 406 x 1 x 1 x 81 = 63733068
Therefore, the lowest common multiple of 812,969,646,486 is 63733068.
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.
812 x 969 x 646 x 486 = 247029371568
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.
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
969 : 1, 3, 17, 19, 51, 57, 323, 969
646 : 1, 2, 17, 19, 34, 38, 323, 646
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 812,969,646,486, is 1.
Now, the common factors can be found like this.
812:2x 2x 7x 29
969:3x 17x 19
646:2x 17x 19
486:2x 3x 3x 3x 3x 3
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 17x 19 = 3876
Therefore, the value for common factors is 3876.
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 = 247029371568/(1x3876)
LCM = 247029371568/3876
LCM = 63733068
Thus, we can understand that the LCM of 812,969,646,486 is 63733068.
