Given numbers are 454,747,554,978
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 454,747,554,978 is 15312419838.
Find LCM of 454,747,554,978 with Prime Factorization
2 | 454, 747, 554, 978 |
3 | 227, 747, 277, 489 |
227, 249, 277, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 227 x 249 x 277 x 163 = 15312419838
Therefore, the lowest common multiple of 454,747,554,978 is 15312419838.
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.
454 x 747 x 554 x 978 = 183749038056
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.
454 : 1, 2, 227, 454
747 : 1, 3, 9, 83, 249, 747
554 : 1, 2, 277, 554
978 : 1, 2, 3, 6, 163, 326, 489, 978
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 454,747,554,978, is 1.
Now, the common factors can be found like this.
454:2x 227
747:3x 3x 83
554:2x 277
978:2x 3x 163
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 3 = 12
Therefore, the value for common factors is 12.
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 = 183749038056/(1x12)
LCM = 183749038056/12
LCM = 15312419838
Thus, we can understand that the LCM of 454,747,554,978 is 15312419838.
