Given numbers are 197,591,245,553
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 197,591,245,553 is 11438805.
Find LCM of 197,591,245,553 with Prime Factorization
| 7 | 197, 591, 245, 553 |
| 197 | 197, 591, 35, 79 |
| 1, 3, 35, 79 |
Multiply the prime numbers at the bottom and the left side.
7 x 197 x 1 x 3 x 35 x 79 = 11438805
Therefore, the lowest common multiple of 197,591,245,553 is 11438805.
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.
197 x 591 x 245 x 553 = 15774112095
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.
197 : 1, 197
591 : 1, 3, 197, 591
245 : 1, 5, 7, 35, 49, 245
553 : 1, 7, 79, 553
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 197,591,245,553, is 1.
Now, the common factors can be found like this.
197:197
591:3x 197
245:5x 7x 7
553:7x 79
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 197 = 1379
Therefore, the value for common factors is 1379.
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 = 15774112095/(1x1379)
LCM = 15774112095/1379
LCM = 11438805
Thus, we can understand that the LCM of 197,591,245,553 is 11438805.
