Given numbers are 305,775,868,217
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 305,775,868,217 is 1323700.
Find LCM of 305,775,868,217 with Prime Factorization
| 5 | 305, 775, 868, 217 |
| 7 | 61, 155, 868, 217 |
| 31 | 61, 155, 124, 31 |
| 61, 5, 4, 1 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 31 x 61 x 5 x 4 x 1 = 1323700
Therefore, the lowest common multiple of 305,775,868,217 is 1323700.
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 775 x 868 x 217 = 44522649500
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
775 : 1, 5, 25, 31, 155, 775
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
217 : 1, 7, 31, 217
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 305,775,868,217, is 1.
Now, the common factors can be found like this.
305:5x 61
775:5x 5x 31
868:2x 2x 7x 31
217:7x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 7x 31x 31 = 33635
Therefore, the value for common factors is 33635.
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 = 44522649500/(1x33635)
LCM = 44522649500/33635
LCM = 1323700
Thus, we can understand that the LCM of 305,775,868,217 is 1323700.
