Given numbers are 921,734,979,957,108
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 921,734,979,957,108 is 345468842532.
Find LCM of 921,734,979,957,108 with Prime Factorization
| 2 | 921, 734, 979, 957, 108 |
| 3 | 921, 367, 979, 957, 54 |
| 11 | 307, 367, 979, 319, 18 |
| 307, 367, 89, 29, 18 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 307 x 367 x 89 x 29 x 18 = 345468842532
Therefore, the lowest common multiple of 921,734,979,957,108 is 345468842532.
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.
921 x 734 x 979 x 957 x 108 = 68402830821336
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.
921 : 1, 3, 307, 921
734 : 1, 2, 367, 734
979 : 1, 11, 89, 979
957 : 1, 3, 11, 29, 33, 87, 319, 957
108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,734,979,957,108, is 1.
Now, the common factors can be found like this.
921:3x 307
734:2x 367
979:11x 89
957:3x 11x 29
108:2x 2x 3x 3x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 11 = 198
Therefore, the value for common factors is 198.
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 = 68402830821336/(1x198)
LCM = 68402830821336/198
LCM = 345468842532
Thus, we can understand that the LCM of 921,734,979,957,108 is 345468842532.
