Given numbers are 521,722,918

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

The LCM of 521,722,918 is 172658358.

Find LCM of 521,722,918 with Prime Factorization

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

2 x 521 x 361 x 459 = 172658358

Therefore, the lowest common multiple of 521,722,918 is 172658358.

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.

521 x 722 x 918 = 345316716

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.

521 : 1, 521

722 : 1, 2, 19, 38, 361, 722

918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 521,722,918, is 1.

Now, the common factors can be found like this.

521:521

722:2x 19x 19

918:2x 3x 3x 3x 17

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

2 = 2

Therefore, the value for common factors is 2.

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 = 345316716/(1x2)

LCM = 345316716/2

LCM = 172658358

Thus, we can understand that the LCM of 521,722,918 is 172658358.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 629, 495, 776
