Find LCM of 676,674,545,988,805 with Prime Factorization
| 2 | 676, 674, 545, 988, 805 |
| 2 | 338, 337, 545, 494, 805 |
| 5 | 169, 337, 545, 247, 805 |
| 13 | 169, 337, 109, 247, 161 |
| 13, 337, 109, 19, 161 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 13 x 13 x 337 x 109 x 19 x 161 = 379797914860
Therefore, the lowest common multiple of 676,674,545,988,805 is 379797914860.
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.
676 x 674 x 545 x 988 x 805 = 197494915727200
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.
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
674 : 1, 2, 337, 674
545 : 1, 5, 109, 545
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
805 : 1, 5, 7, 23, 35, 115, 161, 805
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 676,674,545,988,805, is 1.
Now, the common factors can be found like this.
676:2x 2x 13x 13
674:2x 337
545:5x 109
988:2x 2x 13x 19
805:5x 7x 23
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 5x 13 = 520
Therefore, the value for common factors is 520.
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 = 197494915727200/(1x520)
LCM = 197494915727200/520
LCM = 379797914860
Thus, we can understand that the LCM of 676,674,545,988,805 is 379797914860.
