Find LCM of 933,704,688,989 with Prime Factorization
| 2 | 933, 704, 688, 989 |
| 2 | 933, 352, 344, 989 |
| 2 | 933, 176, 172, 989 |
| 2 | 933, 88, 86, 989 |
| 43 | 933, 44, 43, 989 |
| 933, 44, 1, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 43 x 933 x 44 x 1 x 23 = 649606848
Therefore, the lowest common multiple of 933,704,688,989 is 649606848.
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.
933 x 704 x 688 x 989 = 446929511424
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.
933 : 1, 3, 311, 933
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 933,704,688,989, is 1.
Now, the common factors can be found like this.
933:3x 311
704:2x 2x 2x 2x 2x 2x 11
688:2x 2x 2x 2x 43
989:23x 43
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 43 = 688
Therefore, the value for common factors is 688.
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 = 446929511424/(1x688)
LCM = 446929511424/688
LCM = 649606848
Thus, we can understand that the LCM of 933,704,688,989 is 649606848.
