Given numbers are 217,454,454,845
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 217,454,454,845 is 83247710.
Find LCM of 217,454,454,845 with Prime Factorization
2 | 217, 454, 454, 845 |
227 | 217, 227, 227, 845 |
217, 1, 1, 845 |
Multiply the prime numbers at the bottom and the left side.
2 x 227 x 217 x 1 x 1 x 845 = 83247710
Therefore, the lowest common multiple of 217,454,454,845 is 83247710.
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.
217 x 454 x 454 x 845 = 37794460340
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.
217 : 1, 7, 31, 217
454 : 1, 2, 227, 454
454 : 1, 2, 227, 454
845 : 1, 5, 13, 65, 169, 845
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 217,454,454,845, is 1.
Now, the common factors can be found like this.
217:7x 31
454:2x 227
454:2x 227
845:5x 13x 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 227 = 454
Therefore, the value for common factors is 454.
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 = 37794460340/(1x454)
LCM = 37794460340/454
LCM = 83247710
Thus, we can understand that the LCM of 217,454,454,845 is 83247710.
