Given numbers are 965,991,908,454
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 965,991,908,454 is 868334020.
Find LCM of 965,991,908,454 with Prime Factorization
| 2 | 965, 991, 908, 454 |
| 227 | 965, 991, 454, 227 |
| 965, 991, 2, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 227 x 965 x 991 x 2 x 1 = 868334020
Therefore, the lowest common multiple of 965,991,908,454 is 868334020.
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.
965 x 991 x 908 x 454 = 394223645080
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.
965 : 1, 5, 193, 965
991 : 1, 991
908 : 1, 2, 4, 227, 454, 908
454 : 1, 2, 227, 454
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 965,991,908,454, is 1.
Now, the common factors can be found like this.
965:5x 193
991:991
908:2x 2x 227
454:2x 227
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 227 = 454
Therefore, the value for common factors is 454.
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 = 394223645080/(1x454)
LCM = 394223645080/454
LCM = 868334020
Thus, we can understand that the LCM of 965,991,908,454 is 868334020.
