The LCM of 817,676,988,626 is 172867396.
Find LCM of 817,676,988,626 with Prime Factorization
| 2 | 817, 676, 988, 626 |
| 2 | 817, 338, 494, 313 |
| 13 | 817, 169, 247, 313 |
| 19 | 817, 13, 19, 313 |
| 43, 13, 1, 313 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 19 x 43 x 13 x 1 x 313 = 172867396
Therefore, the lowest common multiple of 817,676,988,626 is 172867396.
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.
817 x 676 x 988 x 626 = 341585974496
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.
817 : 1, 19, 43, 817
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
626 : 1, 2, 313, 626
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 817,676,988,626, is 1.
Now, the common factors can be found like this.
817:19x 43
676:2x 2x 13x 13
988:2x 2x 13x 19
626:2x 313
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 13x 19 = 1976
Therefore, the value for common factors is 1976.
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 = 341585974496/(1x1976)
LCM = 341585974496/1976
LCM = 172867396
Thus, we can understand that the LCM of 817,676,988,626 is 172867396.
