Given numbers are 345,447,123

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

The LCM of 345,447,123 is 2107605.

Find LCM of 345,447,123 with Prime Factorization

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

3 x 115 x 149 x 41 = 2107605

Therefore, the lowest common multiple of 345,447,123 is 2107605.

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.

345 x 447 x 123 = 18968445

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.

345 : 1, 3, 5, 15, 23, 69, 115, 345

447 : 1, 3, 149, 447

123 : 1, 3, 41, 123

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 345,447,123, is 3.

Now, the common factors can be found like this.

345:3x 5x 23

447:3x 149

123:3x 41

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 = 18968445/(3x3)

LCM = 18968445/9

LCM = 2107605

Thus, we can understand that the LCM of 345,447,123 is 2107605.

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

• LCM of 472, 140, 589
• LCM of 300, 882, 630
