Given numbers are 890,160,764,277,728
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 890,160,764,277,728 is 68559006880.
Find LCM of 890,160,764,277,728 with Prime Factorization
| 2 | 890, 160, 764, 277, 728 |
| 2 | 445, 80, 382, 277, 364 |
| 2 | 445, 40, 191, 277, 182 |
| 5 | 445, 20, 191, 277, 91 |
| 89, 4, 191, 277, 91 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 89 x 4 x 191 x 277 x 91 = 68559006880
Therefore, the lowest common multiple of 890,160,764,277,728 is 68559006880.
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.
890 x 160 x 764 x 277 x 728 = 21938882201600
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.
890 : 1, 2, 5, 10, 89, 178, 445, 890
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
764 : 1, 2, 4, 191, 382, 764
277 : 1, 277
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 890,160,764,277,728, is 1.
Now, the common factors can be found like this.
890:2x 5x 89
160:2x 2x 2x 2x 2x 5
764:2x 2x 191
277:277
728:2x 2x 2x 7x 13
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 2x 2x 5 = 320
Therefore, the value for common factors is 320.
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 = 21938882201600/(1x320)
LCM = 21938882201600/320
LCM = 68559006880
Thus, we can understand that the LCM of 890,160,764,277,728 is 68559006880.
