Given numbers are 440,393,890

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

The LCM of 440,393,890 is 15389880.

Find LCM of 440,393,890 with Prime Factorization

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

2 x 5 x 44 x 393 x 89 = 15389880

Therefore, the lowest common multiple of 440,393,890 is 15389880.

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.

440 x 393 x 890 = 153898800

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.

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

393 : 1, 3, 131, 393

890 : 1, 2, 5, 10, 89, 178, 445, 890

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 440,393,890, is 1.

Now, the common factors can be found like this.

440:2x 2x 2x 5x 11

393:3x 131

890:2x 5x 89

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 153898800/(1x10)

LCM = 153898800/10

LCM = 15389880

Thus, we can understand that the LCM of 440,393,890 is 15389880.

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

• LCM of 661, 211, 603
