Find LCM of 634,351,189,546 with Prime Factorization
| 2 | 634, 351, 189, 546 |
| 3 | 317, 351, 189, 273 |
| 3 | 317, 117, 63, 91 |
| 3 | 317, 39, 21, 91 |
| 7 | 317, 13, 7, 91 |
| 13 | 317, 13, 1, 13 |
| 317, 1, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 7 x 13 x 317 x 1 x 1 x 1 = 1557738
Therefore, the lowest common multiple of 634,351,189,546 is 1557738.
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.
634 x 351 x 189 x 546 = 22964173596
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.
634 : 1, 2, 317, 634
351 : 1, 3, 9, 13, 27, 39, 117, 351
189 : 1, 3, 7, 9, 21, 27, 63, 189
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 634,351,189,546, is 1.
Now, the common factors can be found like this.
634:2x 317
351:3x 3x 3x 13
189:3x 3x 3x 7
546:2x 3x 7x 13
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 3x 7x 13 = 14742
Therefore, the value for common factors is 14742.
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 = 22964173596/(1x14742)
LCM = 22964173596/14742
LCM = 1557738
Thus, we can understand that the LCM of 634,351,189,546 is 1557738.
