Given numbers are 43,39,728

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 43,39,728 is 93912.

Find LCM of 43,39,728 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

13 x 43 x 3 x 56 = 93912

Therefore, the lowest common multiple of 43,39,728 is 93912.

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.

43 x 39 x 728 = 1220856

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.

43 : 1, 43

39 : 1, 3, 13, 39

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 43,39,728, is 1.

Now, the common factors can be found like this.

43:43

39:3x 13

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.

13 = 13

Therefore, the value for common factors is 13.

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 = 1220856/(1x13)

LCM = 1220856/13

LCM = 93912

Thus, we can understand that the LCM of 43,39,728 is 93912.
