Given numbers are 382,290,421

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

The LCM of 382,290,421 is 23319190.

Find LCM of 382,290,421 with Prime Factorization

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

2 x 191 x 145 x 421 = 23319190

Therefore, the lowest common multiple of 382,290,421 is 23319190.

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.

382 x 290 x 421 = 46638380

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.

382 : 1, 2, 191, 382

290 : 1, 2, 5, 10, 29, 58, 145, 290

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 382,290,421, is 1.

Now, the common factors can be found like this.

382:2x 191

290:2x 5x 29

421:421

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 = 46638380/(1x2)

LCM = 46638380/2

LCM = 23319190

Thus, we can understand that the LCM of 382,290,421 is 23319190.

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

• LCM of 656, 400, 320
• LCM of 129, 565, 206
