Given numbers are 397,326,142,458

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

The LCM of 397,326,142,458 is 2104272298.

Find LCM of 397,326,142,458 with Prime Factorization

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

2 x 397 x 163 x 71 x 229 = 2104272298

Therefore, the lowest common multiple of 397,326,142,458 is 2104272298.

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.

397 x 326 x 142 x 458 = 8417089192

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.

397 : 1, 397

326 : 1, 2, 163, 326

142 : 1, 2, 71, 142

458 : 1, 2, 229, 458

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,326,142,458, is 1.

Now, the common factors can be found like this.

397:397

326:2x 163

142:2x 71

458:2x 229

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 8417089192/(1x4)

LCM = 8417089192/4

LCM = 2104272298

Thus, we can understand that the LCM of 397,326,142,458 is 2104272298.
