Given numbers are 775,492,813,168
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 775,492,813,168 is 1446652200.
Find LCM of 775,492,813,168 with Prime Factorization
| 2 | 775, 492, 813, 168 |
| 2 | 775, 246, 813, 84 |
| 3 | 775, 123, 813, 42 |
| 775, 41, 271, 14 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 775 x 41 x 271 x 14 = 1446652200
Therefore, the lowest common multiple of 775,492,813,168 is 1446652200.
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.
775 x 492 x 813 x 168 = 52079479200
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.
775 : 1, 5, 25, 31, 155, 775
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
813 : 1, 3, 271, 813
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 775,492,813,168, is 1.
Now, the common factors can be found like this.
775:5x 5x 31
492:2x 2x 3x 41
813:3x 271
168:2x 2x 2x 3x 7
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 3 = 36
Therefore, the value for common factors is 36.
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 = 52079479200/(1x36)
LCM = 52079479200/36
LCM = 1446652200
Thus, we can understand that the LCM of 775,492,813,168 is 1446652200.
