Given numbers are 1,987,517,738
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 1,987,517,738 is 2670822.
Find LCM of 1,987,517,738 with Prime Factorization
| 3 | 1, 987, 517, 738 |
| 47 | 1, 329, 517, 246 |
| 1, 7, 11, 246 |
Multiply the prime numbers at the bottom and the left side.
3 x 47 x 1 x 7 x 11 x 246 = 2670822
Therefore, the lowest common multiple of 1,987,517,738 is 2670822.
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.
1 x 987 x 517 x 738 = 376585902
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.
1 : 1
987 : 1, 3, 7, 21, 47, 141, 329, 987
517 : 1, 11, 47, 517
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1,987,517,738, is 1.
Now, the common factors can be found like this.
1:
987:3x 7x 47
517:11x 47
738:2x 3x 3x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 47 = 141
Therefore, the value for common factors is 141.
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 = 376585902/(1x141)
LCM = 376585902/141
LCM = 2670822
Thus, we can understand that the LCM of 1,987,517,738 is 2670822.
