Given numbers are 438,219,643

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

The LCM of 438,219,643 is 281634.

Find LCM of 438,219,643 with Prime Factorization

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

3 x 73 x 2 x 1 x 643 = 281634

Therefore, the lowest common multiple of 438,219,643 is 281634.

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.

438 x 219 x 643 = 61677846

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.

438 : 1, 2, 3, 6, 73, 146, 219, 438

219 : 1, 3, 73, 219

643 : 1, 643

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 438,219,643, is 1.

Now, the common factors can be found like this.

438:2x 3x 73

219:3x 73

643:643

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

3x 73 = 219

Therefore, the value for common factors is 219.

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 = 61677846/(1x219)

LCM = 61677846/219

LCM = 281634

Thus, we can understand that the LCM of 438,219,643 is 281634.

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

• LCM of 748, 677, 866
