Given numbers are 482,639,238,448
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 482,639,238,448 is 1172856384.
Find LCM of 482,639,238,448 with Prime Factorization
| 2 | 482, 639, 238, 448 |
| 7 | 241, 639, 119, 224 |
| 241, 639, 17, 32 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 241 x 639 x 17 x 32 = 1172856384
Therefore, the lowest common multiple of 482,639,238,448 is 1172856384.
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.
482 x 639 x 238 x 448 = 32839978752
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.
482 : 1, 2, 241, 482
639 : 1, 3, 9, 71, 213, 639
238 : 1, 2, 7, 14, 17, 34, 119, 238
448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 482,639,238,448, is 1.
Now, the common factors can be found like this.
482:2x 241
639:3x 3x 71
238:2x 7x 17
448:2x 2x 2x 2x 2x 2x 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 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 = 32839978752/(1x28)
LCM = 32839978752/28
LCM = 1172856384
Thus, we can understand that the LCM of 482,639,238,448 is 1172856384.
