Calculate the LCM of 157,731,629,731

Given numbers are 157,731,629,731

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

The LCM of 157,731,629,731 is 4246379.

Find LCM of 157,731,629,731 with Prime Factorization


17 157, 731, 629, 731
43 157, 43, 37, 43
157, 1, 37, 1

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

17 x 43 x 157 x 1 x 37 x 1 = 4246379

Therefore, the lowest common multiple of 157,731,629,731 is 4246379.

LCM Formula to Find Lowest Common Multiple of 157,731,629,731

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.

157 x 731 x 629 x 731 = 52769751833

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.

157 : 1, 157

731 : 1, 17, 43, 731

629 : 1, 17, 37, 629

731 : 1, 17, 43, 731

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 157,731,629,731, is 1.

Now, the common factors can be found like this.

157:157

731:17x 43

629:17x 37

731:17x 43

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

17x 17x 43 = 12427

Therefore, the value for common factors is 12427.

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 = 52769751833/(1x12427)

LCM = 52769751833/12427

LCM = 4246379

Thus, we can understand that the LCM of 157,731,629,731 is 4246379.
