Calculate the LCM of 386,491,808,647,435

Given numbers are 386,491,808,647,435

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

The LCM of 386,491,808,647,435 is 21549822608280.

Find LCM of 386,491,808,647,435 with Prime Factorization


2 386, 491, 808, 647, 435
193, 491, 404, 647, 435

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

2 x 193 x 491 x 404 x 647 x 435 = 21549822608280

Therefore, the lowest common multiple of 386,491,808,647,435 is 21549822608280.

LCM Formula to Find Lowest Common Multiple of 386,491,808,647,435

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.

386 x 491 x 808 x 647 x 435 = 43099645216560

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.

386 : 1, 2, 193, 386

491 : 1, 491

808 : 1, 2, 4, 8, 101, 202, 404, 808

647 : 1, 647

435 : 1, 3, 5, 15, 29, 87, 145, 435

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 386,491,808,647,435, is 1.

Now, the common factors can be found like this.

386:2x 193

491:491

808:2x 2x 2x 101

647:647

435:3x 5x 29

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 = 43099645216560/(1x2)

LCM = 43099645216560/2

LCM = 21549822608280

Thus, we can understand that the LCM of 386,491,808,647,435 is 21549822608280.
