Given numbers are 437,551,725,989
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 437,551,725,989 is 13623475.
Find LCM of 437,551,725,989 with Prime Factorization
| 19 | 437, 551, 725, 989 |
| 23 | 23, 29, 725, 989 |
| 29 | 1, 29, 725, 43 |
| 1, 1, 25, 43 |
Multiply the prime numbers at the bottom and the left side.
19 x 23 x 29 x 1 x 1 x 25 x 43 = 13623475
Therefore, the lowest common multiple of 437,551,725,989 is 13623475.
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.
437 x 551 x 725 x 989 = 172650298675
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.
437 : 1, 19, 23, 437
551 : 1, 19, 29, 551
725 : 1, 5, 25, 29, 145, 725
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 437,551,725,989, is 1.
Now, the common factors can be found like this.
437:19x 23
551:19x 29
725:5x 5x 29
989:23x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19x 23x 29 = 12673
Therefore, the value for common factors is 12673.
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 = 172650298675/(1x12673)
LCM = 172650298675/12673
LCM = 13623475
Thus, we can understand that the LCM of 437,551,725,989 is 13623475.
