Given numbers are 143,11,643

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

The LCM of 143,11,643 is 91949.

Find LCM of 143,11,643 with Prime Factorization

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

11 x 13 x 1 x 643 = 91949

Therefore, the lowest common multiple of 143,11,643 is 91949.

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.

143 x 11 x 643 = 1011439

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.

143 : 1, 11, 13, 143

11 : 1, 11

643 : 1, 643

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 143,11,643, is 1.

Now, the common factors can be found like this.

143:11x 13

11:11

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.

11 = 11

Therefore, the value for common factors is 11.

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 = 1011439/(1x11)

LCM = 1011439/11

LCM = 91949

Thus, we can understand that the LCM of 143,11,643 is 91949.

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

• LCM of 193, 15, 307
• LCM of 797, 96, 331
