Find LCM of 648,263,651,691,243 with Prime Factorization
| 3 | 648, 263, 651, 691, 243 |
| 3 | 216, 263, 217, 691, 81 |
| 3 | 72, 263, 217, 691, 27 |
| 3 | 24, 263, 217, 691, 9 |
| 8, 263, 217, 691, 3 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 3 x 8 x 263 x 217 x 691 x 3 = 76663702584
Therefore, the lowest common multiple of 648,263,651,691,243 is 76663702584.
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 263 x 651 x 691 x 243 = 18629279727912
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
263 : 1, 263
651 : 1, 3, 7, 21, 31, 93, 217, 651
691 : 1, 691
243 : 1, 3, 9, 27, 81, 243
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 648,263,651,691,243, is 1.
Now, the common factors can be found like this.
648:2x 2x 2x 3x 3x 3x 3
263:263
651:3x 7x 31
691:691
243:3x 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.
3x 3x 3x 3x 3 = 243
Therefore, the value for common factors is 243.
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 = 18629279727912/(1x243)
LCM = 18629279727912/243
LCM = 76663702584
Thus, we can understand that the LCM of 648,263,651,691,243 is 76663702584.
