Given numbers are 143,121,481,105

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

The LCM of 143,121,481,105 is 6111105.

Find LCM of 143,121,481,105 with Prime Factorization

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

11 x 13 x 1 x 11 x 37 x 105 = 6111105

Therefore, the lowest common multiple of 143,121,481,105 is 6111105.

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 121 x 481 x 105 = 873888015

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

121 : 1, 11, 121

481 : 1, 13, 37, 481

105 : 1, 3, 5, 7, 15, 21, 35, 105

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 143,121,481,105, is 1.

Now, the common factors can be found like this.

143:11x 13

121:11x 11

481:13x 37

105:3x 5x 7

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

11x 13 = 143

Therefore, the value for common factors is 143.

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 = 873888015/(1x143)

LCM = 873888015/143

LCM = 6111105

Thus, we can understand that the LCM of 143,121,481,105 is 6111105.
