Given numbers are 812,580,905,908
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 812,580,905,908 is 166813220.
Find LCM of 812,580,905,908 with Prime Factorization
| 2 | 812, 580, 905, 908 |
| 2 | 406, 290, 905, 454 |
| 5 | 203, 145, 905, 227 |
| 29 | 203, 29, 181, 227 |
| 7, 1, 181, 227 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 29 x 7 x 1 x 181 x 227 = 166813220
Therefore, the lowest common multiple of 812,580,905,908 is 166813220.
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.
812 x 580 x 905 x 908 = 387006670400
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.
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580
905 : 1, 5, 181, 905
908 : 1, 2, 4, 227, 454, 908
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 812,580,905,908, is 1.
Now, the common factors can be found like this.
812:2x 2x 7x 29
580:2x 2x 5x 29
905:5x 181
908:2x 2x 227
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 5x 29 = 2320
Therefore, the value for common factors is 2320.
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 = 387006670400/(1x2320)
LCM = 387006670400/2320
LCM = 166813220
Thus, we can understand that the LCM of 812,580,905,908 is 166813220.
