Given numbers are 381,469,145,469

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

The LCM of 381,469,145,469 is 25909905.

Find LCM of 381,469,145,469 with Prime Factorization

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

7 x 67 x 381 x 1 x 145 x 1 = 25909905

Therefore, the lowest common multiple of 381,469,145,469 is 25909905.

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.

381 x 469 x 145 x 469 = 12151745445

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.

381 : 1, 3, 127, 381

469 : 1, 7, 67, 469

145 : 1, 5, 29, 145

469 : 1, 7, 67, 469

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,469,145,469, is 1.

Now, the common factors can be found like this.

381:3x 127

469:7x 67

145:5x 29

469:7x 67

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

7x 67 = 469

Therefore, the value for common factors is 469.

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 = 12151745445/(1x469)

LCM = 12151745445/469

LCM = 25909905

Thus, we can understand that the LCM of 381,469,145,469 is 25909905.
