Given numbers are 841,100,845,540
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 841,100,845,540 is 383748300.
Find LCM of 841,100,845,540 with Prime Factorization
| 2 | 841, 100, 845, 540 |
| 2 | 841, 50, 845, 270 |
| 5 | 841, 25, 845, 135 |
| 841, 5, 169, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 841 x 5 x 169 x 27 = 383748300
Therefore, the lowest common multiple of 841,100,845,540 is 383748300.
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.
841 x 100 x 845 x 540 = 38374830000
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.
841 : 1, 29, 841
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
845 : 1, 5, 13, 65, 169, 845
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 841,100,845,540, is 1.
Now, the common factors can be found like this.
841:29x 29
100:2x 2x 5x 5
845:5x 13x 13
540:2x 2x 3x 3x 3x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 5x 5 = 100
Therefore, the value for common factors is 100.
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 = 38374830000/(1x100)
LCM = 38374830000/100
LCM = 383748300
Thus, we can understand that the LCM of 841,100,845,540 is 383748300.
