Find LCM of 343,225,557,275,561 with Prime Factorization
| 3 | 343, 225, 557, 275, 561 |
| 5 | 343, 75, 557, 275, 187 |
| 5 | 343, 15, 557, 55, 187 |
| 11 | 343, 3, 557, 11, 187 |
| 343, 3, 557, 1, 17 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 5 x 11 x 343 x 3 x 557 x 1 x 17 = 8038470825
Therefore, the lowest common multiple of 343,225,557,275,561 is 8038470825.
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 225 x 557 x 275 x 561 = 6631738430625
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
225 : 1, 3, 5, 9, 15, 25, 45, 75, 225
557 : 1, 557
275 : 1, 5, 11, 25, 55, 275
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 343,225,557,275,561, is 1.
Now, the common factors can be found like this.
343:7x 7x 7
225:3x 3x 5x 5
557:557
275:5x 5x 11
561:3x 11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 5x 11 = 825
Therefore, the value for common factors is 825.
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 = 6631738430625/(1x825)
LCM = 6631738430625/825
LCM = 8038470825
Thus, we can understand that the LCM of 343,225,557,275,561 is 8038470825.
