Given numbers are 991,999,592,920
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 991,999,592,920 is 1821616560.
Find LCM of 991,999,592,920 with Prime Factorization
| 2 | 991, 999, 592, 920 |
| 2 | 991, 999, 296, 460 |
| 2 | 991, 999, 148, 230 |
| 37 | 991, 999, 74, 115 |
| 991, 27, 2, 115 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 37 x 991 x 27 x 2 x 115 = 1821616560
Therefore, the lowest common multiple of 991,999,592,920 is 1821616560.
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.
991 x 999 x 592 x 920 = 539198501760
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.
991 : 1, 991
999 : 1, 3, 9, 27, 37, 111, 333, 999
592 : 1, 2, 4, 8, 16, 37, 74, 148, 296, 592
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,999,592,920, is 1.
Now, the common factors can be found like this.
991:991
999:3x 3x 3x 37
592:2x 2x 2x 2x 37
920:2x 2x 2x 5x 23
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 2x 37 = 296
Therefore, the value for common factors is 296.
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 = 539198501760/(1x296)
LCM = 539198501760/296
LCM = 1821616560
Thus, we can understand that the LCM of 991,999,592,920 is 1821616560.
