Find LCM of 718,781,198,676,639 with Prime Factorization
| 2 | 718, 781, 198, 676, 639 |
| 3 | 359, 781, 99, 338, 639 |
| 3 | 359, 781, 33, 338, 213 |
| 11 | 359, 781, 11, 338, 71 |
| 71 | 359, 71, 1, 338, 71 |
| 359, 1, 1, 338, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 11 x 71 x 359 x 1 x 1 x 338 x 1 = 1705825836
Therefore, the lowest common multiple of 718,781,198,676,639 is 1705825836.
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.
718 x 781 x 198 x 676 x 639 = 47960999204976
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.
718 : 1, 2, 359, 718
781 : 1, 11, 71, 781
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
639 : 1, 3, 9, 71, 213, 639
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 718,781,198,676,639, is 1.
Now, the common factors can be found like this.
718:2x 359
781:11x 71
198:2x 3x 3x 11
676:2x 2x 13x 13
639:3x 3x 71
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 11x 71 = 28116
Therefore, the value for common factors is 28116.
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 = 47960999204976/(1x28116)
LCM = 47960999204976/28116
LCM = 1705825836
Thus, we can understand that the LCM of 718,781,198,676,639 is 1705825836.
