The LCM of 676,981,663,396 is 124010172.
Find LCM of 676,981,663,396 with Prime Factorization
2 | 676, 981, 663, 396 |
2 | 338, 981, 663, 198 |
3 | 169, 981, 663, 99 |
3 | 169, 327, 221, 33 |
13 | 169, 109, 221, 11 |
13, 109, 17, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 13 x 13 x 109 x 17 x 11 = 124010172
Therefore, the lowest common multiple of 676,981,663,396 is 124010172.
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 981 x 663 x 396 = 174110281488
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
981 : 1, 3, 9, 109, 327, 981
663 : 1, 3, 13, 17, 39, 51, 221, 663
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 676,981,663,396, is 1.
Now, the common factors can be found like this.
676:2x 2x 13x 13
981:3x 3x 109
663:3x 13x 17
396:2x 2x 3x 3x 11
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 13 = 1404
Therefore, the value for common factors is 1404.
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 = 174110281488/(1x1404)
LCM = 174110281488/1404
LCM = 124010172
Thus, we can understand that the LCM of 676,981,663,396 is 124010172.
