Given numbers are 191,378,145,203
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 191,378,145,203 is 10468710.
Find LCM of 191,378,145,203 with Prime Factorization
| 7 | 191, 378, 145, 203 |
| 29 | 191, 54, 145, 29 |
| 191, 54, 5, 1 |
Multiply the prime numbers at the bottom and the left side.
7 x 29 x 191 x 54 x 5 x 1 = 10468710
Therefore, the lowest common multiple of 191,378,145,203 is 10468710.
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.
191 x 378 x 145 x 203 = 2125148130
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.
191 : 1, 191
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
145 : 1, 5, 29, 145
203 : 1, 7, 29, 203
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 191,378,145,203, is 1.
Now, the common factors can be found like this.
191:191
378:2x 3x 3x 3x 7
145:5x 29
203:7x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 29 = 203
Therefore, the value for common factors is 203.
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 = 2125148130/(1x203)
LCM = 2125148130/203
LCM = 10468710
Thus, we can understand that the LCM of 191,378,145,203 is 10468710.
