Find LCM of 356,621,964,621,989 with Prime Factorization
| 2 | 356, 621, 964, 621, 989 |
| 2 | 178, 621, 482, 621, 989 |
| 3 | 89, 621, 241, 621, 989 |
| 3 | 89, 207, 241, 207, 989 |
| 3 | 89, 69, 241, 69, 989 |
| 23 | 89, 23, 241, 23, 989 |
| 89, 1, 241, 1, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 23 x 89 x 1 x 241 x 1 x 43 = 2291010588
Therefore, the lowest common multiple of 356,621,964,621,989 is 2291010588.
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.
356 x 621 x 964 x 621 x 989 = 130890016913616
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.
356 : 1, 2, 4, 89, 178, 356
621 : 1, 3, 9, 23, 27, 69, 207, 621
964 : 1, 2, 4, 241, 482, 964
621 : 1, 3, 9, 23, 27, 69, 207, 621
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 356,621,964,621,989, is 1.
Now, the common factors can be found like this.
356:2x 2x 89
621:3x 3x 3x 23
964:2x 2x 241
621:3x 3x 3x 23
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 3x 3x 3x 23x 23 = 57132
Therefore, the value for common factors is 57132.
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 = 130890016913616/(1x57132)
LCM = 130890016913616/57132
LCM = 2291010588
Thus, we can understand that the LCM of 356,621,964,621,989 is 2291010588.
