Find LCM of 476,308,557,247,221 with Prime Factorization
| 2 | 476, 308, 557, 247, 221 |
| 2 | 238, 154, 557, 247, 221 |
| 7 | 119, 77, 557, 247, 221 |
| 13 | 17, 11, 557, 247, 221 |
| 17 | 17, 11, 557, 19, 17 |
| 1, 11, 557, 19, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 13 x 17 x 1 x 11 x 557 x 19 x 1 = 720363644
Therefore, the lowest common multiple of 476,308,557,247,221 is 720363644.
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.
476 x 308 x 557 x 247 x 221 = 4457610229072
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.
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
557 : 1, 557
247 : 1, 13, 19, 247
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 476,308,557,247,221, is 1.
Now, the common factors can be found like this.
476:2x 2x 7x 17
308:2x 2x 7x 11
557:557
247:13x 19
221:13x 17
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 7x 13x 17 = 6188
Therefore, the value for common factors is 6188.
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 = 4457610229072/(1x6188)
LCM = 4457610229072/6188
LCM = 720363644
Thus, we can understand that the LCM of 476,308,557,247,221 is 720363644.
