Calculate the LCM of 423,957,143

Given numbers are 423,957,143

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

The LCM of 423,957,143 is 1754181.

Find LCM of 423,957,143 with Prime Factorization


3 423, 957, 143
11 141, 319, 143
141, 29, 13

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

3 x 11 x 141 x 29 x 13 = 1754181

Therefore, the lowest common multiple of 423,957,143 is 1754181.

LCM Formula to Find Lowest Common Multiple of 423,957,143

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.

423 x 957 x 143 = 57887973

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.

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

957 : 1, 3, 11, 29, 33, 87, 319, 957

143 : 1, 11, 13, 143

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 423,957,143, is 1.

Now, the common factors can be found like this.

423:3x 3x 47

957:3x 11x 29

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.

3x 11 = 33

Therefore, the value for common factors is 33.

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 = 57887973/(1x33)

LCM = 57887973/33

LCM = 1754181

Thus, we can understand that the LCM of 423,957,143 is 1754181.
