Given numbers are 428,334,170,347

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

The LCM of 428,334,170,347 is 2108184620.

Find LCM of 428,334,170,347 with Prime Factorization

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

2 x 214 x 167 x 85 x 347 = 2108184620

Therefore, the lowest common multiple of 428,334,170,347 is 2108184620.

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.

428 x 334 x 170 x 347 = 8432738480

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.

428 : 1, 2, 4, 107, 214, 428

334 : 1, 2, 167, 334

170 : 1, 2, 5, 10, 17, 34, 85, 170

347 : 1, 347

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,334,170,347, is 1.

Now, the common factors can be found like this.

428:2x 2x 107

334:2x 167

170:2x 5x 17

347:347

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 = 8432738480/(1x4)

LCM = 8432738480/4

LCM = 2108184620

Thus, we can understand that the LCM of 428,334,170,347 is 2108184620.
