Given numbers are 395,689,308,908,828
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 395,689,308,908,828 is 3938793718860.
Find LCM of 395,689,308,908,828 with Prime Factorization
2 | 395, 689, 308, 908, 828 |
2 | 395, 689, 154, 454, 414 |
395, 689, 77, 227, 207 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 395 x 689 x 77 x 227 x 207 = 3938793718860
Therefore, the lowest common multiple of 395,689,308,908,828 is 3938793718860.
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.
395 x 689 x 308 x 908 x 828 = 63020699501760
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.
395 : 1, 5, 79, 395
689 : 1, 13, 53, 689
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
908 : 1, 2, 4, 227, 454, 908
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 395,689,308,908,828, is 1.
Now, the common factors can be found like this.
395:5x 79
689:13x 53
308:2x 2x 7x 11
908:2x 2x 227
828:2x 2x 3x 3x 23
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 2 = 16
Therefore, the value for common factors is 16.
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 = 63020699501760/(1x16)
LCM = 63020699501760/16
LCM = 3938793718860
Thus, we can understand that the LCM of 395,689,308,908,828 is 3938793718860.
