Find LCM of 821,414,102,943,197 with Prime Factorization
| 2 | 821, 414, 102, 943, 197 |
| 3 | 821, 207, 51, 943, 197 |
| 23 | 821, 69, 17, 943, 197 |
| 821, 3, 17, 41, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 821 x 3 x 17 x 41 x 197 = 46670505246
Therefore, the lowest common multiple of 821,414,102,943,197 is 46670505246.
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.
821 x 414 x 102 x 943 x 197 = 6440529723948
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.
821 : 1, 821
414 : 1, 2, 3, 6, 9, 18, 23, 46, 69, 138, 207, 414
102 : 1, 2, 3, 6, 17, 34, 51, 102
943 : 1, 23, 41, 943
197 : 1, 197
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,414,102,943,197, is 1.
Now, the common factors can be found like this.
821:821
414:2x 3x 3x 23
102:2x 3x 17
943:23x 41
197:197
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 23 = 138
Therefore, the value for common factors is 138.
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 = 6440529723948/(1x138)
LCM = 6440529723948/138
LCM = 46670505246
Thus, we can understand that the LCM of 821,414,102,943,197 is 46670505246.
