Given numbers are 424,388,747,257
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 424,388,747,257 is 7895712312.
Find LCM of 424,388,747,257 with Prime Factorization
| 2 | 424, 388, 747, 257 |
| 2 | 212, 194, 747, 257 |
| 106, 97, 747, 257 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 106 x 97 x 747 x 257 = 7895712312
Therefore, the lowest common multiple of 424,388,747,257 is 7895712312.
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.
424 x 388 x 747 x 257 = 31582849248
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.
424 : 1, 2, 4, 8, 53, 106, 212, 424
388 : 1, 2, 4, 97, 194, 388
747 : 1, 3, 9, 83, 249, 747
257 : 1, 257
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 424,388,747,257, is 1.
Now, the common factors can be found like this.
424:2x 2x 2x 53
388:2x 2x 97
747:3x 3x 83
257:257
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 31582849248/(1x4)
LCM = 31582849248/4
LCM = 7895712312
Thus, we can understand that the LCM of 424,388,747,257 is 7895712312.
