Given numbers are 196,841,308,385
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 196,841,308,385 is 9065980.
Find LCM of 196,841,308,385 with Prime Factorization
| 2 | 196, 841, 308, 385 |
| 2 | 98, 841, 154, 385 |
| 7 | 49, 841, 77, 385 |
| 11 | 7, 841, 11, 55 |
| 7, 841, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 11 x 7 x 841 x 1 x 5 = 9065980
Therefore, the lowest common multiple of 196,841,308,385 is 9065980.
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.
196 x 841 x 308 x 385 = 19546252880
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.
196 : 1, 2, 4, 7, 14, 28, 49, 98, 196
841 : 1, 29, 841
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
385 : 1, 5, 7, 11, 35, 55, 77, 385
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 196,841,308,385, is 1.
Now, the common factors can be found like this.
196:2x 2x 7x 7
841:29x 29
308:2x 2x 7x 11
385:5x 7x 11
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 7x 7x 11 = 2156
Therefore, the value for common factors is 2156.
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 = 19546252880/(1x2156)
LCM = 19546252880/2156
LCM = 9065980
Thus, we can understand that the LCM of 196,841,308,385 is 9065980.
