Given numbers are 403,278,398,682

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

The LCM of 403,278,398,682 is 245242426.

Find LCM of 403,278,398,682 with Prime Factorization

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

2 x 31 x 13 x 139 x 199 x 11 = 245242426

Therefore, the lowest common multiple of 403,278,398,682 is 245242426.

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.

403 x 278 x 398 x 682 = 30410060824

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.

403 : 1, 13, 31, 403

278 : 1, 2, 139, 278

398 : 1, 2, 199, 398

682 : 1, 2, 11, 22, 31, 62, 341, 682

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,278,398,682, is 1.

Now, the common factors can be found like this.

403:13x 31

278:2x 139

398:2x 199

682:2x 11x 31

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

2x 2x 31 = 124

Therefore, the value for common factors is 124.

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 = 30410060824/(1x124)

LCM = 30410060824/124

LCM = 245242426

Thus, we can understand that the LCM of 403,278,398,682 is 245242426.
