Find LCM of 966,414,668,721 with Prime Factorization
| 2 | 966, 414, 668, 721 |
| 3 | 483, 207, 334, 721 |
| 7 | 161, 69, 334, 721 |
| 23 | 23, 69, 334, 103 |
| 1, 3, 334, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 23 x 1 x 3 x 334 x 103 = 99696996
Therefore, the lowest common multiple of 966,414,668,721 is 99696996.
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.
966 x 414 x 668 x 721 = 192614596272
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.
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
414 : 1, 2, 3, 6, 9, 18, 23, 46, 69, 138, 207, 414
668 : 1, 2, 4, 167, 334, 668
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 966,414,668,721, is 1.
Now, the common factors can be found like this.
966:2x 3x 7x 23
414:2x 3x 3x 23
668:2x 2x 167
721:7x 103
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 7x 23 = 1932
Therefore, the value for common factors is 1932.
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 = 192614596272/(1x1932)
LCM = 192614596272/1932
LCM = 99696996
Thus, we can understand that the LCM of 966,414,668,721 is 99696996.
