Given numbers are 395,398,842

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

The LCM of 395,398,842 is 66185410.

Find LCM of 395,398,842 with Prime Factorization

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

2 x 395 x 199 x 421 = 66185410

Therefore, the lowest common multiple of 395,398,842 is 66185410.

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.

395 x 398 x 842 = 132370820

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.

395 : 1, 5, 79, 395

398 : 1, 2, 199, 398

842 : 1, 2, 421, 842

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 395,398,842, is 1.

Now, the common factors can be found like this.

395:5x 79

398:2x 199

842:2x 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 = 132370820/(1x2)

LCM = 132370820/2

LCM = 66185410

Thus, we can understand that the LCM of 395,398,842 is 66185410.

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

• LCM of 990, 265, 290
• LCM of 788, 496, 850
