Find LCM of 427,209,189,558,642 with Prime Factorization
| 2 | 427, 209, 189, 558, 642 |
| 3 | 427, 209, 189, 279, 321 |
| 3 | 427, 209, 63, 93, 107 |
| 7 | 427, 209, 21, 31, 107 |
| 61, 209, 3, 31, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 61 x 209 x 3 x 31 x 107 = 15985027674
Therefore, the lowest common multiple of 427,209,189,558,642 is 15985027674.
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.
427 x 209 x 189 x 558 x 642 = 6042340460772
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.
427 : 1, 7, 61, 427
209 : 1, 11, 19, 209
189 : 1, 3, 7, 9, 21, 27, 63, 189
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 427,209,189,558,642, is 1.
Now, the common factors can be found like this.
427:7x 61
209:11x 19
189:3x 3x 3x 7
558:2x 3x 3x 31
642:2x 3x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 7 = 378
Therefore, the value for common factors is 378.
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 = 6042340460772/(1x378)
LCM = 6042340460772/378
LCM = 15985027674
Thus, we can understand that the LCM of 427,209,189,558,642 is 15985027674.
