Given numbers are 422,142,618,381

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

The LCM of 422,142,618,381 is 1175798766.

Find LCM of 422,142,618,381 with Prime Factorization

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

2 x 3 x 211 x 71 x 103 x 127 = 1175798766

Therefore, the lowest common multiple of 422,142,618,381 is 1175798766.

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.

422 x 142 x 618 x 381 = 14109585192

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.

422 : 1, 2, 211, 422

142 : 1, 2, 71, 142

618 : 1, 2, 3, 6, 103, 206, 309, 618

381 : 1, 3, 127, 381

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,142,618,381, is 1.

Now, the common factors can be found like this.

422:2x 211

142:2x 71

618:2x 3x 103

381:3x 127

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 3 = 12

Therefore, the value for common factors is 12.

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 = 14109585192/(1x12)

LCM = 14109585192/12

LCM = 1175798766

Thus, we can understand that the LCM of 422,142,618,381 is 1175798766.
