Given numbers are 161,489,321

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

The LCM of 161,489,321 is 8424003.

Find LCM of 161,489,321 with Prime Factorization

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

3 x 161 x 163 x 107 = 8424003

Therefore, the lowest common multiple of 161,489,321 is 8424003.

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.

161 x 489 x 321 = 25272009

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.

161 : 1, 7, 23, 161

489 : 1, 3, 163, 489

321 : 1, 3, 107, 321

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,489,321, is 1.

Now, the common factors can be found like this.

161:7x 23

489:3x 163

321:3x 107

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

3 = 3

Therefore, the value for common factors is 3.

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 = 25272009/(1x3)

LCM = 25272009/3

LCM = 8424003

Thus, we can understand that the LCM of 161,489,321 is 8424003.

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

• LCM of 695, 897, 298
• LCM of 742, 460, 978
