Given numbers are 969,662,981,938,666
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 969,662,981,938,666 is 3640022649018.
Find LCM of 969,662,981,938,666 with Prime Factorization
| 2 | 969, 662, 981, 938, 666 |
| 3 | 969, 331, 981, 469, 333 |
| 3 | 323, 331, 327, 469, 111 |
| 323, 331, 109, 469, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 323 x 331 x 109 x 469 x 37 = 3640022649018
Therefore, the lowest common multiple of 969,662,981,938,666 is 3640022649018.
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.
969 x 662 x 981 x 938 x 666 = 393122446093944
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.
969 : 1, 3, 17, 19, 51, 57, 323, 969
662 : 1, 2, 331, 662
981 : 1, 3, 9, 109, 327, 981
938 : 1, 2, 7, 14, 67, 134, 469, 938
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 969,662,981,938,666, is 1.
Now, the common factors can be found like this.
969:3x 17x 19
662:2x 331
981:3x 3x 109
938:2x 7x 67
666:2x 3x 3x 37
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 3 = 108
Therefore, the value for common factors is 108.
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 = 393122446093944/(1x108)
LCM = 393122446093944/108
LCM = 3640022649018
Thus, we can understand that the LCM of 969,662,981,938,666 is 3640022649018.
