Calculate the LCM of 731,321,639,983

Given numbers are 731,321,639,983

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

The LCM of 731,321,639,983 is 49130991729.

Find LCM of 731,321,639,983 with Prime Factorization


3 731, 321, 639, 983
731, 107, 213, 983

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

3 x 731 x 107 x 213 x 983 = 49130991729

Therefore, the lowest common multiple of 731,321,639,983 is 49130991729.

LCM Formula to Find Lowest Common Multiple of 731,321,639,983

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.

731 x 321 x 639 x 983 = 147392975187

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.

731 : 1, 17, 43, 731

321 : 1, 3, 107, 321

639 : 1, 3, 9, 71, 213, 639

983 : 1, 983

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,321,639,983, is 1.

Now, the common factors can be found like this.

731:17x 43

321:3x 107

639:3x 3x 71

983:983

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

3 = 3

Therefore, the value for common factors is 3.

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 = 147392975187/(1x3)

LCM = 147392975187/3

LCM = 49130991729

Thus, we can understand that the LCM of 731,321,639,983 is 49130991729.
