Given numbers are 250,517,987,387
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 250,517,987,387 is 350138250.
Find LCM of 250,517,987,387 with Prime Factorization
| 3 | 250, 517, 987, 387 |
| 47 | 250, 517, 329, 129 |
| 250, 11, 7, 129 |
Multiply the prime numbers at the bottom and the left side.
3 x 47 x 250 x 11 x 7 x 129 = 350138250
Therefore, the lowest common multiple of 250,517,987,387 is 350138250.
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.
250 x 517 x 987 x 387 = 49369493250
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.
250 : 1, 2, 5, 10, 25, 50, 125, 250
517 : 1, 11, 47, 517
987 : 1, 3, 7, 21, 47, 141, 329, 987
387 : 1, 3, 9, 43, 129, 387
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 250,517,987,387, is 1.
Now, the common factors can be found like this.
250:2x 5x 5x 5
517:11x 47
987:3x 7x 47
387:3x 3x 43
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 = 49369493250/(1x141)
LCM = 49369493250/141
LCM = 350138250
Thus, we can understand that the LCM of 250,517,987,387 is 350138250.
