Given numbers are 128,516,987,948,587
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 128,516,987,948,587 is 251918911104.
Find LCM of 128,516,987,948,587 with Prime Factorization
| 2 | 128, 516, 987, 948, 587 |
| 2 | 64, 258, 987, 474, 587 |
| 3 | 32, 129, 987, 237, 587 |
| 32, 43, 329, 79, 587 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 32 x 43 x 329 x 79 x 587 = 251918911104
Therefore, the lowest common multiple of 128,516,987,948,587 is 251918911104.
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.
128 x 516 x 987 x 948 x 587 = 36276323198976
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.
128 : 1, 2, 4, 8, 16, 32, 64, 128
516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516
987 : 1, 3, 7, 21, 47, 141, 329, 987
948 : 1, 2, 3, 4, 6, 12, 79, 158, 237, 316, 474, 948
587 : 1, 587
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,516,987,948,587, is 1.
Now, the common factors can be found like this.
128:2x 2x 2x 2x 2x 2x 2
516:2x 2x 3x 43
987:3x 7x 47
948:2x 2x 3x 79
587:587
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 36276323198976/(1x144)
LCM = 36276323198976/144
LCM = 251918911104
Thus, we can understand that the LCM of 128,516,987,948,587 is 251918911104.
