Given numbers are 831,541,660,25
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 831,541,660,25 is 494528100.
Find LCM of 831,541,660,25 with Prime Factorization
| 3 | 831, 541, 660, 25 |
| 5 | 277, 541, 220, 25 |
| 277, 541, 44, 5 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 277 x 541 x 44 x 5 = 494528100
Therefore, the lowest common multiple of 831,541,660,25 is 494528100.
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.
831 x 541 x 660 x 25 = 7417921500
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.
831 : 1, 3, 277, 831
541 : 1, 541
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
25 : 1, 5, 25
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,541,660,25, is 1.
Now, the common factors can be found like this.
831:3x 277
541:541
660:2x 2x 3x 5x 11
25:5x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5 = 15
Therefore, the value for common factors is 15.
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 = 7417921500/(1x15)
LCM = 7417921500/15
LCM = 494528100
Thus, we can understand that the LCM of 831,541,660,25 is 494528100.
