Given numbers are 428,573,326,815

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

The LCM of 428,573,326,815 is 199873860.

Find LCM of 428,573,326,815 with Prime Factorization

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

2 x 163 x 214 x 573 x 1 x 5 = 199873860

Therefore, the lowest common multiple of 428,573,326,815 is 199873860.

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 573 x 326 x 815 = 65158878360

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

573 : 1, 3, 191, 573

326 : 1, 2, 163, 326

815 : 1, 5, 163, 815

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,573,326,815, is 1.

Now, the common factors can be found like this.

428:2x 2x 107

573:3x 191

326:2x 163

815:5x 163

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

2x 163 = 326

Therefore, the value for common factors is 326.

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 = 65158878360/(1x326)

LCM = 65158878360/326

LCM = 199873860

Thus, we can understand that the LCM of 428,573,326,815 is 199873860.
