Given numbers are 197,774,591,783
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 197,774,591,783 is 13265586.
Find LCM of 197,774,591,783 with Prime Factorization
| 3 | 197, 774, 591, 783 |
| 3 | 197, 258, 197, 261 |
| 197 | 197, 86, 197, 87 |
| 1, 86, 1, 87 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 197 x 1 x 86 x 1 x 87 = 13265586
Therefore, the lowest common multiple of 197,774,591,783 is 13265586.
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 774 x 591 x 783 = 70559651934
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
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
591 : 1, 3, 197, 591
783 : 1, 3, 9, 27, 29, 87, 261, 783
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 197,774,591,783, is 1.
Now, the common factors can be found like this.
197:197
774:2x 3x 3x 43
591:3x 197
783:3x 3x 3x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 197 = 5319
Therefore, the value for common factors is 5319.
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 = 70559651934/(1x5319)
LCM = 70559651934/5319
LCM = 13265586
Thus, we can understand that the LCM of 197,774,591,783 is 13265586.
