Given numbers are 813,140,203,992
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 813,140,203,992 is 818593440.
Find LCM of 813,140,203,992 with Prime Factorization
| 2 | 813, 140, 203, 992 |
| 2 | 813, 70, 203, 496 |
| 7 | 813, 35, 203, 248 |
| 813, 5, 29, 248 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 813 x 5 x 29 x 248 = 818593440
Therefore, the lowest common multiple of 813,140,203,992 is 818593440.
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.
813 x 140 x 203 x 992 = 22920616320
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.
813 : 1, 3, 271, 813
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
203 : 1, 7, 29, 203
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,140,203,992, is 1.
Now, the common factors can be found like this.
813:3x 271
140:2x 2x 5x 7
203:7x 29
992:2x 2x 2x 2x 2x 31
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 7 = 28
Therefore, the value for common factors is 28.
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 = 22920616320/(1x28)
LCM = 22920616320/28
LCM = 818593440
Thus, we can understand that the LCM of 813,140,203,992 is 818593440.
