Given numbers are 428,166,747,875

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

The LCM of 428,166,747,875 is 279751500.

Find LCM of 428,166,747,875 with Prime Factorization

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

2 x 83 x 214 x 1 x 9 x 875 = 279751500

Therefore, the lowest common multiple of 428,166,747,875 is 279751500.

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 166 x 747 x 875 = 46438749000

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

166 : 1, 2, 83, 166

747 : 1, 3, 9, 83, 249, 747

875 : 1, 5, 7, 25, 35, 125, 175, 875

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,166,747,875, is 1.

Now, the common factors can be found like this.

428:2x 2x 107

166:2x 83

747:3x 3x 83

875:5x 5x 5x 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 83 = 166

Therefore, the value for common factors is 166.

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 = 46438749000/(1x166)

LCM = 46438749000/166

LCM = 279751500

Thus, we can understand that the LCM of 428,166,747,875 is 279751500.
