Given numbers are 484,152,280,644
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 484,152,280,644 is 14805560.
Find LCM of 484,152,280,644 with Prime Factorization
| 2 | 484, 152, 280, 644 |
| 2 | 242, 76, 140, 322 |
| 2 | 121, 38, 70, 161 |
| 7 | 121, 19, 35, 161 |
| 121, 19, 5, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 121 x 19 x 5 x 23 = 14805560
Therefore, the lowest common multiple of 484,152,280,644 is 14805560.
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.
484 x 152 x 280 x 644 = 13265781760
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.
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
152 : 1, 2, 4, 8, 19, 38, 76, 152
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 484,152,280,644, is 4.
Now, the common factors can be found like this.
484:2x 2x 11x 11
152:2x 2x 2x 19
280:2x 2x 2x 5x 7
644:2x 2x 7x 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 2x 7 = 224
Therefore, the value for common factors is 224.
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 = 13265781760/(4x224)
LCM = 13265781760/896
LCM = 14805560
Thus, we can understand that the LCM of 484,152,280,644 is 14805560.
