Find LCM of 343,284,555,756,385 with Prime Factorization
| 2 | 343, 284, 555, 756, 385 |
| 2 | 343, 142, 555, 378, 385 |
| 3 | 343, 71, 555, 189, 385 |
| 5 | 343, 71, 185, 63, 385 |
| 7 | 343, 71, 37, 63, 77 |
| 49, 71, 37, 9, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 49 x 71 x 37 x 9 x 11 = 5352302340
Therefore, the lowest common multiple of 343,284,555,756,385 is 5352302340.
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.
343 x 284 x 555 x 756 x 385 = 15735768879600
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.
343 : 1, 7, 49, 343
284 : 1, 2, 4, 71, 142, 284
555 : 1, 3, 5, 15, 37, 111, 185, 555
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
385 : 1, 5, 7, 11, 35, 55, 77, 385
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 343,284,555,756,385, is 1.
Now, the common factors can be found like this.
343:7x 7x 7
284:2x 2x 71
555:3x 5x 37
756:2x 2x 3x 3x 3x 7
385:5x 7x 11
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 3x 5x 7x 7 = 2940
Therefore, the value for common factors is 2940.
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 = 15735768879600/(1x2940)
LCM = 15735768879600/2940
LCM = 5352302340
Thus, we can understand that the LCM of 343,284,555,756,385 is 5352302340.
