Given numbers are 251,481,962,489
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 251,481,962,489 is 118074918.
Find LCM of 251,481,962,489 with Prime Factorization
| 13 | 251, 481, 962, 489 |
| 37 | 251, 37, 74, 489 |
| 251, 1, 2, 489 |
Multiply the prime numbers at the bottom and the left side.
13 x 37 x 251 x 1 x 2 x 489 = 118074918
Therefore, the lowest common multiple of 251,481,962,489 is 118074918.
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.
251 x 481 x 962 x 489 = 56794035558
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.
251 : 1, 251
481 : 1, 13, 37, 481
962 : 1, 2, 13, 26, 37, 74, 481, 962
489 : 1, 3, 163, 489
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 251,481,962,489, is 1.
Now, the common factors can be found like this.
251:251
481:13x 37
962:2x 13x 37
489:3x 163
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 37 = 481
Therefore, the value for common factors is 481.
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 = 56794035558/(1x481)
LCM = 56794035558/481
LCM = 118074918
Thus, we can understand that the LCM of 251,481,962,489 is 118074918.
