Given numbers are 295,728,789,921,538
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 295,728,789,921,538 is 13993329288120.
Find LCM of 295,728,789,921,538 with Prime Factorization
2 | 295, 728, 789, 921, 538 |
3 | 295, 364, 789, 921, 269 |
295, 364, 263, 307, 269 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 295 x 364 x 263 x 307 x 269 = 13993329288120
Therefore, the lowest common multiple of 295,728,789,921,538 is 13993329288120.
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.
295 x 728 x 789 x 921 x 538 = 83959975728720
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.
295 : 1, 5, 59, 295
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
789 : 1, 3, 263, 789
921 : 1, 3, 307, 921
538 : 1, 2, 269, 538
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 295,728,789,921,538, is 1.
Now, the common factors can be found like this.
295:5x 59
728:2x 2x 2x 7x 13
789:3x 263
921:3x 307
538:2x 269
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 83959975728720/(1x6)
LCM = 83959975728720/6
LCM = 13993329288120
Thus, we can understand that the LCM of 295,728,789,921,538 is 13993329288120.
