Find LCM of 696,894,988,403,821 with Prime Factorization
| 2 | 696, 894, 988, 403, 821 |
| 2 | 348, 447, 494, 403, 821 |
| 3 | 174, 447, 247, 403, 821 |
| 13 | 58, 149, 247, 403, 821 |
| 58, 149, 19, 31, 821 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 58 x 149 x 19 x 31 x 821 = 651924514488
Therefore, the lowest common multiple of 696,894,988,403,821 is 651924514488.
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.
696 x 894 x 988 x 403 x 821 = 203400448520256
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.
696 : 1, 2, 3, 4, 6, 8, 12, 24, 29, 58, 87, 116, 174, 232, 348, 696
894 : 1, 2, 3, 6, 149, 298, 447, 894
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
403 : 1, 13, 31, 403
821 : 1, 821
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 696,894,988,403,821, is 1.
Now, the common factors can be found like this.
696:2x 2x 2x 3x 29
894:2x 3x 149
988:2x 2x 13x 19
403:13x 31
821:821
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 3x 13 = 312
Therefore, the value for common factors is 312.
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 = 203400448520256/(1x312)
LCM = 203400448520256/312
LCM = 651924514488
Thus, we can understand that the LCM of 696,894,988,403,821 is 651924514488.
