Given numbers are 297,665,209,523,178
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 297,665,209,523,178 is 18386530470.
Find LCM of 297,665,209,523,178 with Prime Factorization
| 11 | 297, 665, 209, 523, 178 |
| 19 | 27, 665, 19, 523, 178 |
| 27, 35, 1, 523, 178 |
Multiply the prime numbers at the bottom and the left side.
11 x 19 x 27 x 35 x 1 x 523 x 178 = 18386530470
Therefore, the lowest common multiple of 297,665,209,523,178 is 18386530470.
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.
297 x 665 x 209 x 523 x 178 = 3842784868230
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.
297 : 1, 3, 9, 11, 27, 33, 99, 297
665 : 1, 5, 7, 19, 35, 95, 133, 665
209 : 1, 11, 19, 209
523 : 1, 523
178 : 1, 2, 89, 178
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 297,665,209,523,178, is 1.
Now, the common factors can be found like this.
297:3x 3x 3x 11
665:5x 7x 19
209:11x 19
523:523
178:2x 89
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 19 = 209
Therefore, the value for common factors is 209.
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 = 3842784868230/(1x209)
LCM = 3842784868230/209
LCM = 18386530470
Thus, we can understand that the LCM of 297,665,209,523,178 is 18386530470.
