Given numbers are 512,284,905,697,915
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 512,284,905,697,915 is 4196244226560.
Find LCM of 512,284,905,697,915 with Prime Factorization
| 2 | 512, 284, 905, 697, 915 |
| 2 | 256, 142, 905, 697, 915 |
| 5 | 128, 71, 905, 697, 915 |
| 128, 71, 181, 697, 183 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 128 x 71 x 181 x 697 x 183 = 4196244226560
Therefore, the lowest common multiple of 512,284,905,697,915 is 4196244226560.
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.
512 x 284 x 905 x 697 x 915 = 83924884531200
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.
512 : 1, 2, 4, 8, 16, 32, 64, 128, 256, 512
284 : 1, 2, 4, 71, 142, 284
905 : 1, 5, 181, 905
697 : 1, 17, 41, 697
915 : 1, 3, 5, 15, 61, 183, 305, 915
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 512,284,905,697,915, is 1.
Now, the common factors can be found like this.
512:2x 2x 2x 2x 2x 2x 2x 2x 2
284:2x 2x 71
905:5x 181
697:17x 41
915:3x 5x 61
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 5 = 20
Therefore, the value for common factors is 20.
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 = 83924884531200/(1x20)
LCM = 83924884531200/20
LCM = 4196244226560
Thus, we can understand that the LCM of 512,284,905,697,915 is 4196244226560.
