Given numbers are 843,556,180,720
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 843,556,180,720 is 28122480.
Find LCM of 843,556,180,720 with Prime Factorization
| 2 | 843, 556, 180, 720 |
| 2 | 843, 278, 90, 360 |
| 3 | 843, 139, 45, 180 |
| 3 | 281, 139, 15, 60 |
| 5 | 281, 139, 5, 20 |
| 281, 139, 1, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 281 x 139 x 1 x 4 = 28122480
Therefore, the lowest common multiple of 843,556,180,720 is 28122480.
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.
843 x 556 x 180 x 720 = 60744556800
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.
843 : 1, 3, 281, 843
556 : 1, 2, 4, 139, 278, 556
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 843,556,180,720, is 1.
Now, the common factors can be found like this.
843:3x 281
556:2x 2x 139
180:2x 2x 3x 3x 5
720:2x 2x 2x 2x 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 2x 2x 3x 3x 3x 5 = 2160
Therefore, the value for common factors is 2160.
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 = 60744556800/(1x2160)
LCM = 60744556800/2160
LCM = 28122480
Thus, we can understand that the LCM of 843,556,180,720 is 28122480.
