Calculate the LCM of 320,464,556

Given numbers are 320,464,556

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

The LCM of 320,464,556 is 1289920.

Find LCM of 320,464,556 with Prime Factorization


2 320, 464, 556
2 160, 232, 278
2 80, 116, 139
2 40, 58, 139
20, 29, 139

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

2 x 2 x 2 x 2 x 20 x 29 x 139 = 1289920

Therefore, the lowest common multiple of 320,464,556 is 1289920.

LCM Formula to Find Lowest Common Multiple of 320,464,556

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.

320 x 464 x 556 = 82554880

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.

320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320

464 : 1, 2, 4, 8, 16, 29, 58, 116, 232, 464

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

4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 320,464,556, is 4.

Now, the common factors can be found like this.

320:2x 2x 2x 2x 2x 2x 5

464:2x 2x 2x 2x 29

556:2x 2x 139

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 2 = 16

Therefore, the value for common factors is 16.

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 = 82554880/(4x16)

LCM = 82554880/64

LCM = 1289920

Thus, we can understand that the LCM of 320,464,556 is 1289920.
