Given numbers are 839,451,561,728
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 839,451,561,728 is 14048826792.
Find LCM of 839,451,561,728 with Prime Factorization
11 | 839, 451, 561, 728 |
839, 41, 51, 728 |
Multiply the prime numbers at the bottom and the left side.
11 x 839 x 41 x 51 x 728 = 14048826792
Therefore, the lowest common multiple of 839,451,561,728 is 14048826792.
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.
839 x 451 x 561 x 728 = 154537094712
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.
839 : 1, 839
451 : 1, 11, 41, 451
561 : 1, 3, 11, 17, 33, 51, 187, 561
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 839,451,561,728, is 1.
Now, the common factors can be found like this.
839:839
451:11x 41
561:3x 11x 17
728:2x 2x 2x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 154537094712/(1x11)
LCM = 154537094712/11
LCM = 14048826792
Thus, we can understand that the LCM of 839,451,561,728 is 14048826792.
