Given numbers are 235,421,831,352,987
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 235,421,831,352,987 is 202577723040.
Find LCM of 235,421,831,352,987 with Prime Factorization
| 3 | 235, 421, 831, 352, 987 |
| 47 | 235, 421, 277, 352, 329 |
| 5, 421, 277, 352, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 47 x 5 x 421 x 277 x 352 x 7 = 202577723040
Therefore, the lowest common multiple of 235,421,831,352,987 is 202577723040.
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.
235 x 421 x 831 x 352 x 987 = 28563458948640
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.
235 : 1, 5, 47, 235
421 : 1, 421
831 : 1, 3, 277, 831
352 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 88, 176, 352
987 : 1, 3, 7, 21, 47, 141, 329, 987
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 235,421,831,352,987, is 1.
Now, the common factors can be found like this.
235:5x 47
421:421
831:3x 277
352:2x 2x 2x 2x 2x 11
987:3x 7x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 47 = 141
Therefore, the value for common factors is 141.
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 = 28563458948640/(1x141)
LCM = 28563458948640/141
LCM = 202577723040
Thus, we can understand that the LCM of 235,421,831,352,987 is 202577723040.
