Given numbers are 454,637,988,144
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 454,637,988,144 is 395622864.
Find LCM of 454,637,988,144 with Prime Factorization
| 2 | 454, 637, 988, 144 |
| 2 | 227, 637, 494, 72 |
| 13 | 227, 637, 247, 36 |
| 227, 49, 19, 36 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 227 x 49 x 19 x 36 = 395622864
Therefore, the lowest common multiple of 454,637,988,144 is 395622864.
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 637 x 988 x 144 = 41144777856
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
637 : 1, 7, 13, 49, 91, 637
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 454,637,988,144, is 1.
Now, the common factors can be found like this.
454:2x 227
637:7x 7x 13
988:2x 2x 13x 19
144:2x 2x 2x 2x 3x 3
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 13 = 104
Therefore, the value for common factors is 104.
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 = 41144777856/(1x104)
LCM = 41144777856/104
LCM = 395622864
Thus, we can understand that the LCM of 454,637,988,144 is 395622864.
