The LCM of 407,243,840,263,165 is 7283069640.
Find LCM of 407,243,840,263,165 with Prime Factorization
3 | 407, 243, 840, 263, 165 |
5 | 407, 81, 280, 263, 55 |
11 | 407, 81, 56, 263, 11 |
37, 81, 56, 263, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 37 x 81 x 56 x 263 x 1 = 7283069640
Therefore, the lowest common multiple of 407,243,840,263,165 is 7283069640.
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.
407 x 243 x 840 x 263 x 165 = 3605119471800
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.
407 : 1, 11, 37, 407
243 : 1, 3, 9, 27, 81, 243
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
263 : 1, 263
165 : 1, 3, 5, 11, 15, 33, 55, 165
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 407,243,840,263,165, is 1.
Now, the common factors can be found like this.
407:11x 37
243:3x 3x 3x 3x 3
840:2x 2x 2x 3x 5x 7
263:263
165:3x 5x 11
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 5x 11 = 495
Therefore, the value for common factors is 495.
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 = 3605119471800/(1x495)
LCM = 3605119471800/495
LCM = 7283069640
Thus, we can understand that the LCM of 407,243,840,263,165 is 7283069640.
