Given numbers are 128,844,507,568
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 128,844,507,568 is 972206976.
Find LCM of 128,844,507,568 with Prime Factorization
| 2 | 128, 844, 507, 568 |
| 2 | 64, 422, 507, 284 |
| 2 | 32, 211, 507, 142 |
| 16, 211, 507, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 16 x 211 x 507 x 71 = 972206976
Therefore, the lowest common multiple of 128,844,507,568 is 972206976.
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 844 x 507 x 568 = 31110623232
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
844 : 1, 2, 4, 211, 422, 844
507 : 1, 3, 13, 39, 169, 507
568 : 1, 2, 4, 8, 71, 142, 284, 568
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,844,507,568, is 1.
Now, the common factors can be found like this.
128:2x 2x 2x 2x 2x 2x 2
844:2x 2x 211
507:3x 13x 13
568:2x 2x 2x 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 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 = 31110623232/(1x32)
LCM = 31110623232/32
LCM = 972206976
Thus, we can understand that the LCM of 128,844,507,568 is 972206976.
