Calculate the LCM of 317,340,402,613,643

Given numbers are 317,340,402,613,643

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

The LCM of 317,340,402,613,643 is 8538973861020.

Find LCM of 317,340,402,613,643 with Prime Factorization


2 317, 340, 402, 613, 643
317, 170, 201, 613, 643

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

2 x 317 x 170 x 201 x 613 x 643 = 8538973861020

Therefore, the lowest common multiple of 317,340,402,613,643 is 8538973861020.

LCM Formula to Find Lowest Common Multiple of 317,340,402,613,643

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.

317 x 340 x 402 x 613 x 643 = 17077947722040

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.

317 : 1, 317

340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340

402 : 1, 2, 3, 6, 67, 134, 201, 402

613 : 1, 613

643 : 1, 643

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 317,340,402,613,643, is 1.

Now, the common factors can be found like this.

317:317

340:2x 2x 5x 17

402:2x 3x 67

613:613

643:643

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 = 17077947722040/(1x2)

LCM = 17077947722040/2

LCM = 8538973861020

Thus, we can understand that the LCM of 317,340,402,613,643 is 8538973861020.
