Find LCM of 584,405,378,756 with Prime Factorization
| 2 | 584, 405, 378, 756 |
| 2 | 292, 405, 189, 378 |
| 3 | 146, 405, 189, 189 |
| 3 | 146, 135, 63, 63 |
| 3 | 146, 45, 21, 21 |
| 7 | 146, 15, 7, 7 |
| 146, 15, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 7 x 146 x 15 x 1 x 1 = 1655640
Therefore, the lowest common multiple of 584,405,378,756 is 1655640.
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.
584 x 405 x 378 x 756 = 67589847360
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.
584 : 1, 2, 4, 8, 73, 146, 292, 584
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 584,405,378,756, is 1.
Now, the common factors can be found like this.
584:2x 2x 2x 73
405:3x 3x 3x 3x 5
378:2x 3x 3x 3x 7
756:2x 2x 3x 3x 3x 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 2x 2x 3x 3x 3x 3x 3x 3x 7 = 40824
Therefore, the value for common factors is 40824.
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 = 67589847360/(1x40824)
LCM = 67589847360/40824
LCM = 1655640
Thus, we can understand that the LCM of 584,405,378,756 is 1655640.
