The LCM of 381,504,746,441 is 167124888.
Find LCM of 381,504,746,441 with Prime Factorization
| 2 | 381, 504, 746, 441 |
| 3 | 381, 252, 373, 441 |
| 3 | 127, 84, 373, 147 |
| 7 | 127, 28, 373, 49 |
| 127, 4, 373, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 127 x 4 x 373 x 7 = 167124888
Therefore, the lowest common multiple of 381,504,746,441 is 167124888.
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.
381 x 504 x 746 x 441 = 63173207664
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.
381 : 1, 3, 127, 381
504 : 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, 504
746 : 1, 2, 373, 746
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,504,746,441, is 1.
Now, the common factors can be found like this.
381:3x 127
504:2x 2x 2x 3x 3x 7
746:2x 373
441:3x 3x 7x 7
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 = 63173207664/(1x378)
LCM = 63173207664/378
LCM = 167124888
Thus, we can understand that the LCM of 381,504,746,441 is 167124888.
