Given numbers are 152,121,388,656
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 152,121,388,656 is 146289968.
Find LCM of 152,121,388,656 with Prime Factorization
| 2 | 152, 121, 388, 656 |
| 2 | 76, 121, 194, 328 |
| 2 | 38, 121, 97, 164 |
| 19, 121, 97, 82 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 19 x 121 x 97 x 82 = 146289968
Therefore, the lowest common multiple of 152,121,388,656 is 146289968.
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.
152 x 121 x 388 x 656 = 4681278976
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.
152 : 1, 2, 4, 8, 19, 38, 76, 152
121 : 1, 11, 121
388 : 1, 2, 4, 97, 194, 388
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 152,121,388,656, is 1.
Now, the common factors can be found like this.
152:2x 2x 2x 19
121:11x 11
388:2x 2x 97
656:2x 2x 2x 2x 41
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 2 = 32
Therefore, the value for common factors is 32.
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 = 4681278976/(1x32)
LCM = 4681278976/32
LCM = 146289968
Thus, we can understand that the LCM of 152,121,388,656 is 146289968.
