Find LCM of 904,778,791,688,579 with Prime Factorization
| 2 | 904, 778, 791, 688, 579 |
| 2 | 452, 389, 791, 344, 579 |
| 2 | 226, 389, 791, 172, 579 |
| 113 | 113, 389, 791, 86, 579 |
| 1, 389, 7, 86, 579 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 113 x 1 x 389 x 7 x 86 x 579 = 122572512048
Therefore, the lowest common multiple of 904,778,791,688,579 is 122572512048.
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.
904 x 778 x 791 x 688 x 579 = 221611101782784
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.
904 : 1, 2, 4, 8, 113, 226, 452, 904
778 : 1, 2, 389, 778
791 : 1, 7, 113, 791
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
579 : 1, 3, 193, 579
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 904,778,791,688,579, is 1.
Now, the common factors can be found like this.
904:2x 2x 2x 113
778:2x 389
791:7x 113
688:2x 2x 2x 2x 43
579:3x 193
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 113 = 1808
Therefore, the value for common factors is 1808.
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 = 221611101782784/(1x1808)
LCM = 221611101782784/1808
LCM = 122572512048
Thus, we can understand that the LCM of 904,778,791,688,579 is 122572512048.
