Given numbers are 388,247,262,871,923
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 388,247,262,871,923 is 59721832612.
Find LCM of 388,247,262,871,923 with Prime Factorization
| 2 | 388, 247, 262, 871, 923 |
| 13 | 194, 247, 131, 871, 923 |
| 194, 19, 131, 67, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 194 x 19 x 131 x 67 x 71 = 59721832612
Therefore, the lowest common multiple of 388,247,262,871,923 is 59721832612.
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.
388 x 247 x 262 x 871 x 923 = 20185979422856
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.
388 : 1, 2, 4, 97, 194, 388
247 : 1, 13, 19, 247
262 : 1, 2, 131, 262
871 : 1, 13, 67, 871
923 : 1, 13, 71, 923
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,247,262,871,923, is 1.
Now, the common factors can be found like this.
388:2x 2x 97
247:13x 19
262:2x 131
871:13x 67
923:13x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 13 = 338
Therefore, the value for common factors is 338.
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 = 20185979422856/(1x338)
LCM = 20185979422856/338
LCM = 59721832612
Thus, we can understand that the LCM of 388,247,262,871,923 is 59721832612.
