Find LCM of 270,243,407,720,477 with Prime Factorization
| 2 | 270, 243, 407, 720, 477 |
| 3 | 135, 243, 407, 360, 477 |
| 3 | 45, 81, 407, 120, 159 |
| 3 | 15, 27, 407, 40, 53 |
| 5 | 5, 9, 407, 40, 53 |
| 1, 9, 407, 8, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 5 x 1 x 9 x 407 x 8 x 53 = 419340240
Therefore, the lowest common multiple of 270,243,407,720,477 is 419340240.
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.
270 x 243 x 407 x 720 x 477 = 9170971048800
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.
270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270
243 : 1, 3, 9, 27, 81, 243
407 : 1, 11, 37, 407
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
477 : 1, 3, 9, 53, 159, 477
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 270,243,407,720,477, is 1.
Now, the common factors can be found like this.
270:2x 3x 3x 3x 5
243:3x 3x 3x 3x 3
407:11x 37
720:2x 2x 2x 2x 3x 3x 5
477:3x 3x 53
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 3x 3x 3x 5 = 21870
Therefore, the value for common factors is 21870.
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 = 9170971048800/(1x21870)
LCM = 9170971048800/21870
LCM = 419340240
Thus, we can understand that the LCM of 270,243,407,720,477 is 419340240.
