Given numbers are 642,166,302

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

The LCM of 642,166,302 is 8046186.

Find LCM of 642,166,302 with Prime Factorization

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

2 x 321 x 83 x 151 = 8046186

Therefore, the lowest common multiple of 642,166,302 is 8046186.

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.

642 x 166 x 302 = 32184744

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.

642 : 1, 2, 3, 6, 107, 214, 321, 642

166 : 1, 2, 83, 166

302 : 1, 2, 151, 302

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,166,302, is 2.

Now, the common factors can be found like this.

642:2x 3x 107

166:2x 83

302:2x 151

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

2 = 2

Therefore, the value for common factors is 2.

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 = 32184744/(2x2)

LCM = 32184744/4

LCM = 8046186

Thus, we can understand that the LCM of 642,166,302 is 8046186.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 247, 473, 223
• LCM of 886, 103, 275
