Given numbers are 983,810,987,385
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 983,810,987,385 is 2881556370.
Find LCM of 983,810,987,385 with Prime Factorization
3 | 983, 810, 987, 385 |
5 | 983, 270, 329, 385 |
7 | 983, 54, 329, 77 |
983, 54, 47, 11 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 983 x 54 x 47 x 11 = 2881556370
Therefore, the lowest common multiple of 983,810,987,385 is 2881556370.
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.
983 x 810 x 987 x 385 = 302563418850
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.
983 : 1, 983
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
987 : 1, 3, 7, 21, 47, 141, 329, 987
385 : 1, 5, 7, 11, 35, 55, 77, 385
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 983,810,987,385, is 1.
Now, the common factors can be found like this.
983:983
810:2x 3x 3x 3x 3x 5
987:3x 7x 47
385:5x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 7 = 105
Therefore, the value for common factors is 105.
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 = 302563418850/(1x105)
LCM = 302563418850/105
LCM = 2881556370
Thus, we can understand that the LCM of 983,810,987,385 is 2881556370.
