Given numbers are 128,591,300,359,921
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 128,591,300,359,921 is 208434825600.
Find LCM of 128,591,300,359,921 with Prime Factorization
| 2 | 128, 591, 300, 359, 921 |
| 2 | 64, 591, 150, 359, 921 |
| 3 | 32, 591, 75, 359, 921 |
| 32, 197, 25, 359, 307 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 32 x 197 x 25 x 359 x 307 = 208434825600
Therefore, the lowest common multiple of 128,591,300,359,921 is 208434825600.
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 591 x 300 x 359 x 921 = 7503653721600
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
591 : 1, 3, 197, 591
300 : 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 25, 30, 50, 60, 75, 100, 150, 300
359 : 1, 359
921 : 1, 3, 307, 921
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,591,300,359,921, is 1.
Now, the common factors can be found like this.
128:2x 2x 2x 2x 2x 2x 2
591:3x 197
300:2x 2x 3x 5x 5
359:359
921:3x 307
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 3x 3 = 36
Therefore, the value for common factors is 36.
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 = 7503653721600/(1x36)
LCM = 7503653721600/36
LCM = 208434825600
Thus, we can understand that the LCM of 128,591,300,359,921 is 208434825600.
