Find LCM of 778,636,836,496,496 with Prime Factorization
| 2 | 778, 636, 836, 496, 496 |
| 2 | 389, 318, 418, 248, 248 |
| 2 | 389, 159, 209, 124, 124 |
| 2 | 389, 159, 209, 62, 62 |
| 31 | 389, 159, 209, 31, 31 |
| 389, 159, 209, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 31 x 389 x 159 x 209 x 1 x 1 = 6411722064
Therefore, the lowest common multiple of 778,636,836,496,496 is 6411722064.
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.
778 x 636 x 836 x 496 x 496 = 101766852599808
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.
778 : 1, 2, 389, 778
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
496 : 1, 2, 4, 8, 16, 31, 62, 124, 248, 496
496 : 1, 2, 4, 8, 16, 31, 62, 124, 248, 496
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,636,836,496,496, is 2.
Now, the common factors can be found like this.
778:2x 389
636:2x 2x 3x 53
836:2x 2x 11x 19
496:2x 2x 2x 2x 31
496:2x 2x 2x 2x 31
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 2x 2x 2x 2x 2x 31 = 7936
Therefore, the value for common factors is 7936.
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 = 101766852599808/(2x7936)
LCM = 101766852599808/15872
LCM = 6411722064
Thus, we can understand that the LCM of 778,636,836,496,496 is 6411722064.
