Given numbers are 916,308,436,506
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 916,308,436,506 is 176823724.
Find LCM of 916,308,436,506 with Prime Factorization
| 2 | 916, 308, 436, 506 |
| 2 | 458, 154, 218, 253 |
| 11 | 229, 77, 109, 253 |
| 229, 7, 109, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 229 x 7 x 109 x 23 = 176823724
Therefore, the lowest common multiple of 916,308,436,506 is 176823724.
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.
916 x 308 x 436 x 506 = 62241950848
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.
916 : 1, 2, 4, 229, 458, 916
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
436 : 1, 2, 4, 109, 218, 436
506 : 1, 2, 11, 22, 23, 46, 253, 506
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 916,308,436,506, is 2.
Now, the common factors can be found like this.
916:2x 2x 229
308:2x 2x 7x 11
436:2x 2x 109
506:2x 11x 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 2x 11 = 176
Therefore, the value for common factors is 176.
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 = 62241950848/(2x176)
LCM = 62241950848/352
LCM = 176823724
Thus, we can understand that the LCM of 916,308,436,506 is 176823724.
