Find LCM of 648,198,721,927 with Prime Factorization
| 2 | 648, 198, 721, 927 |
| 3 | 324, 99, 721, 927 |
| 3 | 108, 33, 721, 309 |
| 103 | 36, 11, 721, 103 |
| 36, 11, 7, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 103 x 36 x 11 x 7 x 1 = 5139288
Therefore, the lowest common multiple of 648,198,721,927 is 5139288.
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.
648 x 198 x 721 x 927 = 85754159568
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.
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
721 : 1, 7, 103, 721
927 : 1, 3, 9, 103, 309, 927
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 648,198,721,927, is 1.
Now, the common factors can be found like this.
648:2x 2x 2x 3x 3x 3x 3
198:2x 3x 3x 11
721:7x 103
927:3x 3x 103
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 3x 103 = 16686
Therefore, the value for common factors is 16686.
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 = 85754159568/(1x16686)
LCM = 85754159568/16686
LCM = 5139288
Thus, we can understand that the LCM of 648,198,721,927 is 5139288.
