The LCM of 671,352,436,494,380 is 2890453280.
Find LCM of 671,352,436,494,380 with Prime Factorization
| 2 | 671, 352, 436, 494, 380 |
| 2 | 671, 176, 218, 247, 190 |
| 11 | 671, 88, 109, 247, 95 |
| 19 | 61, 8, 109, 247, 95 |
| 61, 8, 109, 13, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 19 x 61 x 8 x 109 x 13 x 5 = 2890453280
Therefore, the lowest common multiple of 671,352,436,494,380 is 2890453280.
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.
671 x 352 x 436 x 494 x 380 = 19331351536640
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.
671 : 1, 11, 61, 671
352 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 88, 176, 352
436 : 1, 2, 4, 109, 218, 436
494 : 1, 2, 13, 19, 26, 38, 247, 494
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,352,436,494,380, is 1.
Now, the common factors can be found like this.
671:11x 61
352:2x 2x 2x 2x 2x 11
436:2x 2x 109
494:2x 13x 19
380:2x 2x 5x 19
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 2x 2x 11x 19 = 6688
Therefore, the value for common factors is 6688.
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 = 19331351536640/(1x6688)
LCM = 19331351536640/6688
LCM = 2890453280
Thus, we can understand that the LCM of 671,352,436,494,380 is 2890453280.
