Given numbers are 627,641,543

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

The LCM of 627,641,543 is 72745167.

Find LCM of 627,641,543 with Prime Factorization

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

3 x 209 x 641 x 181 = 72745167

Therefore, the lowest common multiple of 627,641,543 is 72745167.

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.

627 x 641 x 543 = 218235501

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.

627 : 1, 3, 11, 19, 33, 57, 209, 627

641 : 1, 641

543 : 1, 3, 181, 543

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 627,641,543, is 1.

Now, the common factors can be found like this.

627:3x 11x 19

641:641

543:3x 181

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 = 218235501/(1x3)

LCM = 218235501/3

LCM = 72745167

Thus, we can understand that the LCM of 627,641,543 is 72745167.

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

• LCM of 780, 959, 356
• LCM of 560, 551, 875
