Given numbers are 321,440,517

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

The LCM of 321,440,517 is 6638280.

Find LCM of 321,440,517 with Prime Factorization

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

11 x 321 x 40 x 47 = 6638280

Therefore, the lowest common multiple of 321,440,517 is 6638280.

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.

321 x 440 x 517 = 73021080

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.

321 : 1, 3, 107, 321

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

517 : 1, 11, 47, 517

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 321,440,517, is 1.

Now, the common factors can be found like this.

321:3x 107

440:2x 2x 2x 5x 11

517:11x 47

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

11 = 11

Therefore, the value for common factors is 11.

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 = 73021080/(1x11)

LCM = 73021080/11

LCM = 6638280

Thus, we can understand that the LCM of 321,440,517 is 6638280.

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

• LCM of 644, 958, 937
