Calculate the LCM of 406,641,380,821,531

Given numbers are 406,641,380,821,531

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

The LCM of 406,641,380,821,531 is 21556355749740.

Find LCM of 406,641,380,821,531 with Prime Factorization


2 406, 641, 380, 821, 531
203, 641, 190, 821, 531

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

2 x 203 x 641 x 190 x 821 x 531 = 21556355749740

Therefore, the lowest common multiple of 406,641,380,821,531 is 21556355749740.

LCM Formula to Find Lowest Common Multiple of 406,641,380,821,531

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.

406 x 641 x 380 x 821 x 531 = 43112711499480

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.

406 : 1, 2, 7, 14, 29, 58, 203, 406

641 : 1, 641

380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380

821 : 1, 821

531 : 1, 3, 9, 59, 177, 531

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 406,641,380,821,531, is 1.

Now, the common factors can be found like this.

406:2x 7x 29

641:641

380:2x 2x 5x 19

821:821

531:3x 3x 59

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 = 43112711499480/(1x2)

LCM = 43112711499480/2

LCM = 21556355749740

Thus, we can understand that the LCM of 406,641,380,821,531 is 21556355749740.
