Calculate the LCM of 143,105,423,959,217

Given numbers are 143,105,423,959,217

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

The LCM of 143,105,423,959,217 is 8991387405.

Find LCM of 143,105,423,959,217 with Prime Factorization


3 143, 105, 423, 959, 217
7 143, 35, 141, 959, 217
143, 5, 141, 137, 31

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

3 x 7 x 143 x 5 x 141 x 137 x 31 = 8991387405

Therefore, the lowest common multiple of 143,105,423,959,217 is 8991387405.

LCM Formula to Find Lowest Common Multiple of 143,105,423,959,217

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 105 x 423 x 959 x 217 = 1321733948535

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

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

423 : 1, 3, 9, 47, 141, 423

959 : 1, 7, 137, 959

217 : 1, 7, 31, 217

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 143,105,423,959,217, is 1.

Now, the common factors can be found like this.

143:11x 13

105:3x 5x 7

423:3x 3x 47

959:7x 137

217:7x 31

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

3x 7x 7 = 147

Therefore, the value for common factors is 147.

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 = 1321733948535/(1x147)

LCM = 1321733948535/147

LCM = 8991387405

Thus, we can understand that the LCM of 143,105,423,959,217 is 8991387405.
