The LCM of 442,387,496,380,774 is 4030032240.
Find LCM of 442,387,496,380,774 with Prime Factorization
| 2 | 442, 387, 496, 380, 774 |
| 2 | 221, 387, 248, 190, 387 |
| 3 | 221, 387, 124, 95, 387 |
| 3 | 221, 129, 124, 95, 129 |
| 43 | 221, 43, 124, 95, 43 |
| 221, 1, 124, 95, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 43 x 221 x 1 x 124 x 95 x 1 = 4030032240
Therefore, the lowest common multiple of 442,387,496,380,774 is 4030032240.
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.
442 x 387 x 496 x 380 x 774 = 24953959630080
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.
442 : 1, 2, 13, 17, 26, 34, 221, 442
387 : 1, 3, 9, 43, 129, 387
496 : 1, 2, 4, 8, 16, 31, 62, 124, 248, 496
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 442,387,496,380,774, is 1.
Now, the common factors can be found like this.
442:2x 13x 17
387:3x 3x 43
496:2x 2x 2x 2x 31
380:2x 2x 5x 19
774:2x 3x 3x 43
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 2x 2x 3x 3x 43 = 6192
Therefore, the value for common factors is 6192.
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 = 24953959630080/(1x6192)
LCM = 24953959630080/6192
LCM = 4030032240
Thus, we can understand that the LCM of 442,387,496,380,774 is 4030032240.
