Calculate the LCM of 438,542,313

Given numbers are 438,542,313

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

The LCM of 438,542,313 is 37152474.

Find LCM of 438,542,313 with Prime Factorization


2 438, 542, 313
219, 271, 313

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

2 x 219 x 271 x 313 = 37152474

Therefore, the lowest common multiple of 438,542,313 is 37152474.

LCM Formula to Find Lowest Common Multiple of 438,542,313

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.

438 x 542 x 313 = 74304948

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.

438 : 1, 2, 3, 6, 73, 146, 219, 438

542 : 1, 2, 271, 542

313 : 1, 313

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 438,542,313, is 1.

Now, the common factors can be found like this.

438:2x 3x 73

542:2x 271

313:313

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

2 = 2

Therefore, the value for common factors is 2.

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 = 74304948/(1x2)

LCM = 74304948/2

LCM = 37152474

Thus, we can understand that the LCM of 438,542,313 is 37152474.
