Find LCM of 812,921,459,567 with Prime Factorization
| 3 | 812, 921, 459, 567 |
| 3 | 812, 307, 153, 189 |
| 3 | 812, 307, 51, 63 |
| 7 | 812, 307, 17, 21 |
| 116, 307, 17, 3 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 7 x 116 x 307 x 17 x 3 = 343264068
Therefore, the lowest common multiple of 812,921,459,567 is 343264068.
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 921 x 459 x 567 = 194630726556
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
921 : 1, 3, 307, 921
459 : 1, 3, 9, 17, 27, 51, 153, 459
567 : 1, 3, 7, 9, 21, 27, 63, 81, 189, 567
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 812,921,459,567, is 1.
Now, the common factors can be found like this.
812:2x 2x 7x 29
921:3x 307
459:3x 3x 3x 17
567:3x 3x 3x 3x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 7 = 567
Therefore, the value for common factors is 567.
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 = 194630726556/(1x567)
LCM = 194630726556/567
LCM = 343264068
Thus, we can understand that the LCM of 812,921,459,567 is 343264068.
