Find LCM of 318,522,681,580,405 with Prime Factorization
| 2 | 318, 522, 681, 580, 405 |
| 3 | 159, 261, 681, 290, 405 |
| 3 | 53, 87, 227, 290, 135 |
| 5 | 53, 29, 227, 290, 45 |
| 29 | 53, 29, 227, 58, 9 |
| 53, 1, 227, 2, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 29 x 53 x 1 x 227 x 2 x 9 = 565216380
Therefore, the lowest common multiple of 318,522,681,580,405 is 565216380.
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.
318 x 522 x 681 x 580 x 405 = 26553865532400
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.
318 : 1, 2, 3, 6, 53, 106, 159, 318
522 : 1, 2, 3, 6, 9, 18, 29, 58, 87, 174, 261, 522
681 : 1, 3, 227, 681
580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 318,522,681,580,405, is 1.
Now, the common factors can be found like this.
318:2x 3x 53
522:2x 3x 3x 29
681:3x 227
580:2x 2x 5x 29
405:3x 3x 3x 3x 5
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 3x 3x 3x 5x 29 = 46980
Therefore, the value for common factors is 46980.
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 = 26553865532400/(1x46980)
LCM = 26553865532400/46980
LCM = 565216380
Thus, we can understand that the LCM of 318,522,681,580,405 is 565216380.
