Find LCM of 261,557,294,588,580 with Prime Factorization
| 2 | 261, 557, 294, 588, 580 |
| 2 | 261, 557, 147, 294, 290 |
| 3 | 261, 557, 147, 147, 145 |
| 7 | 87, 557, 49, 49, 145 |
| 7 | 87, 557, 7, 7, 145 |
| 29 | 87, 557, 1, 1, 145 |
| 3, 557, 1, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 7 x 29 x 3 x 557 x 1 x 1 x 5 = 142469460
Therefore, the lowest common multiple of 261,557,294,588,580 is 142469460.
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.
261 x 557 x 294 x 588 x 580 = 14576335391520
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.
261 : 1, 3, 9, 29, 87, 261
557 : 1, 557
294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294
588 : 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 49, 84, 98, 147, 196, 294, 588
580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 261,557,294,588,580, is 1.
Now, the common factors can be found like this.
261:3x 3x 29
557:557
294:2x 3x 7x 7
588:2x 2x 3x 7x 7
580:2x 2x 5x 29
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 7x 7x 29 = 102312
Therefore, the value for common factors is 102312.
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 = 14576335391520/(1x102312)
LCM = 14576335391520/102312
LCM = 142469460
Thus, we can understand that the LCM of 261,557,294,588,580 is 142469460.
