Given numbers are 712,978,979,911
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 712,978,979,911 is 3488991528.
Find LCM of 712,978,979,911 with Prime Factorization
| 2 | 712, 978, 979, 911 |
| 89 | 356, 489, 979, 911 |
| 4, 489, 11, 911 |
Multiply the prime numbers at the bottom and the left side.
2 x 89 x 4 x 489 x 11 x 911 = 3488991528
Therefore, the lowest common multiple of 712,978,979,911 is 3488991528.
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.
712 x 978 x 979 x 911 = 621040491984
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.
712 : 1, 2, 4, 8, 89, 178, 356, 712
978 : 1, 2, 3, 6, 163, 326, 489, 978
979 : 1, 11, 89, 979
911 : 1, 911
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 712,978,979,911, is 1.
Now, the common factors can be found like this.
712:2x 2x 2x 89
978:2x 3x 163
979:11x 89
911:911
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 89 = 178
Therefore, the value for common factors is 178.
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 = 621040491984/(1x178)
LCM = 621040491984/178
LCM = 3488991528
Thus, we can understand that the LCM of 712,978,979,911 is 3488991528.
