Given numbers are 481,221,143

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

The LCM of 481,221,143 is 89947.

Find LCM of 481,221,143 with Prime Factorization

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

13 x 37 x 17 x 11 = 89947

Therefore, the lowest common multiple of 481,221,143 is 89947.

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.

481 x 221 x 143 = 15201043

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.

481 : 1, 13, 37, 481

221 : 1, 13, 17, 221

143 : 1, 11, 13, 143

13 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 481,221,143, is 13.

Now, the common factors can be found like this.

481:13x 37

221:13x 17

143:11x 13

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

13 = 13

Therefore, the value for common factors is 13.

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 = 15201043/(13x13)

LCM = 15201043/169

LCM = 89947

Thus, we can understand that the LCM of 481,221,143 is 89947.

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

• LCM of 306, 668, 347
• LCM of 317, 246, 116
