Given numbers are 305,124,308,713,905
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 305,124,308,713,905 is 12123238820.
Find LCM of 305,124,308,713,905 with Prime Factorization
| 2 | 305, 124, 308, 713, 905 |
| 2 | 305, 62, 154, 713, 905 |
| 5 | 305, 31, 77, 713, 905 |
| 31 | 61, 31, 77, 713, 181 |
| 61, 1, 77, 23, 181 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 31 x 61 x 1 x 77 x 23 x 181 = 12123238820
Therefore, the lowest common multiple of 305,124,308,713,905 is 12123238820.
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.
305 x 124 x 308 x 713 x 905 = 7516408068400
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.
305 : 1, 5, 61, 305
124 : 1, 2, 4, 31, 62, 124
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
713 : 1, 23, 31, 713
905 : 1, 5, 181, 905
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 305,124,308,713,905, is 1.
Now, the common factors can be found like this.
305:5x 61
124:2x 2x 31
308:2x 2x 7x 11
713:23x 31
905:5x 181
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 5x 31 = 620
Therefore, the value for common factors is 620.
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 = 7516408068400/(1x620)
LCM = 7516408068400/620
LCM = 12123238820
Thus, we can understand that the LCM of 305,124,308,713,905 is 12123238820.
