Find LCM of 819,310,763,676,635 with Prime Factorization
| 2 | 819, 310, 763, 676, 635 |
| 5 | 819, 155, 763, 338, 635 |
| 7 | 819, 31, 763, 338, 127 |
| 13 | 117, 31, 109, 338, 127 |
| 9, 31, 109, 26, 127 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 13 x 9 x 31 x 109 x 26 x 127 = 91379581020
Therefore, the lowest common multiple of 819,310,763,676,635 is 91379581020.
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.
819 x 310 x 763 x 676 x 635 = 83155418728200
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.
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
310 : 1, 2, 5, 10, 31, 62, 155, 310
763 : 1, 7, 109, 763
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
635 : 1, 5, 127, 635
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 819,310,763,676,635, is 1.
Now, the common factors can be found like this.
819:3x 3x 7x 13
310:2x 5x 31
763:7x 109
676:2x 2x 13x 13
635:5x 127
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 7x 13 = 910
Therefore, the value for common factors is 910.
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 = 83155418728200/(1x910)
LCM = 83155418728200/910
LCM = 91379581020
Thus, we can understand that the LCM of 819,310,763,676,635 is 91379581020.
