Calculate the LCM of 728,556,547,574

Given numbers are 728,556,547,574

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

The LCM of 728,556,547,574 is 2269432984.

Find LCM of 728,556,547,574 with Prime Factorization


2 728, 556, 547, 574
2 364, 278, 547, 287
7 182, 139, 547, 287
26, 139, 547, 41

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

2 x 2 x 7 x 26 x 139 x 547 x 41 = 2269432984

Therefore, the lowest common multiple of 728,556,547,574 is 2269432984.

LCM Formula to Find Lowest Common Multiple of 728,556,547,574

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 556 x 547 x 574 = 127088247104

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

556 : 1, 2, 4, 139, 278, 556

547 : 1, 547

574 : 1, 2, 7, 14, 41, 82, 287, 574

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,556,547,574, is 1.

Now, the common factors can be found like this.

728:2x 2x 2x 7x 13

556:2x 2x 139

547:547

574:2x 7x 41

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 2x 7 = 56

Therefore, the value for common factors is 56.

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 = 127088247104/(1x56)

LCM = 127088247104/56

LCM = 2269432984

Thus, we can understand that the LCM of 728,556,547,574 is 2269432984.
