Given numbers are 378,209,242,506
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 378,209,242,506 is 19987506.
Find LCM of 378,209,242,506 with Prime Factorization
| 2 | 378, 209, 242, 506 |
| 11 | 189, 209, 121, 253 |
| 189, 19, 11, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 189 x 19 x 11 x 23 = 19987506
Therefore, the lowest common multiple of 378,209,242,506 is 19987506.
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.
378 x 209 x 242 x 506 = 9673952904
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.
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
209 : 1, 11, 19, 209
242 : 1, 2, 11, 22, 121, 242
506 : 1, 2, 11, 22, 23, 46, 253, 506
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 378,209,242,506, is 1.
Now, the common factors can be found like this.
378:2x 3x 3x 3x 7
209:11x 19
242:2x 11x 11
506:2x 11x 23
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 11x 11 = 484
Therefore, the value for common factors is 484.
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 = 9673952904/(1x484)
LCM = 9673952904/484
LCM = 19987506
Thus, we can understand that the LCM of 378,209,242,506 is 19987506.
