Given numbers are 725,983,638,987,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 725,983,638,987,638 is 15475024950.
Find LCM of 725,983,638,987,638 with Prime Factorization
2 | 725, 983, 638, 987, 638 |
11 | 725, 983, 319, 987, 319 |
29 | 725, 983, 29, 987, 29 |
25, 983, 1, 987, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 29 x 25 x 983 x 1 x 987 x 1 = 15475024950
Therefore, the lowest common multiple of 725,983,638,987,638 is 15475024950.
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.
725 x 983 x 638 x 987 x 638 = 286318911624900
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.
725 : 1, 5, 25, 29, 145, 725
983 : 1, 983
638 : 1, 2, 11, 22, 29, 58, 319, 638
987 : 1, 3, 7, 21, 47, 141, 329, 987
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 725,983,638,987,638, is 1.
Now, the common factors can be found like this.
725:5x 5x 29
983:983
638:2x 11x 29
987:3x 7x 47
638:2x 11x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 29x 29 = 18502
Therefore, the value for common factors is 18502.
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 = 286318911624900/(1x18502)
LCM = 286318911624900/18502
LCM = 15475024950
Thus, we can understand that the LCM of 725,983,638,987,638 is 15475024950.
