Given numbers are 728,195,611

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

The LCM of 728,195,611 is 513240.

Find LCM of 728,195,611 with Prime Factorization

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

13 x 56 x 15 x 47 = 513240

Therefore, the lowest common multiple of 728,195,611 is 513240.

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.

728 x 195 x 611 = 86737560

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.

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

195 : 1, 3, 5, 13, 15, 39, 65, 195

611 : 1, 13, 47, 611

13 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,195,611, is 13.

Now, the common factors can be found like this.

728:2x 2x 2x 7x 13

195:3x 5x 13

611:13x 47

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 = 86737560/(13x13)

LCM = 86737560/169

LCM = 513240

Thus, we can understand that the LCM of 728,195,611 is 513240.
