Given numbers are 428,556,887,189

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

The LCM of 428,556,887,189 is 9973417356.

Find LCM of 428,556,887,189 with Prime Factorization

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

2 x 2 x 107 x 139 x 887 x 189 = 9973417356

Therefore, the lowest common multiple of 428,556,887,189 is 9973417356.

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 556 x 887 x 189 = 39893669424

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

556 : 1, 2, 4, 139, 278, 556

887 : 1, 887

189 : 1, 3, 7, 9, 21, 27, 63, 189

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,556,887,189, is 1.

Now, the common factors can be found like this.

428:2x 2x 107

556:2x 2x 139

887:887

189:3x 3x 3x 7

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 = 39893669424/(1x4)

LCM = 39893669424/4

LCM = 9973417356

Thus, we can understand that the LCM of 428,556,887,189 is 9973417356.
