Calculate the LCM of 521,380,100,841

Given numbers are 521,380,100,841

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

The LCM of 521,380,100,841 is 832505900.

Find LCM of 521,380,100,841 with Prime Factorization


2 521, 380, 100, 841
2 521, 190, 50, 841
5 521, 95, 25, 841
521, 19, 5, 841

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

2 x 2 x 5 x 521 x 19 x 5 x 841 = 832505900

Therefore, the lowest common multiple of 521,380,100,841 is 832505900.

LCM Formula to Find Lowest Common Multiple of 521,380,100,841

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.

521 x 380 x 100 x 841 = 16650118000

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.

521 : 1, 521

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

100 : 1, 2, 4, 5, 10, 20, 25, 50, 100

841 : 1, 29, 841

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 521,380,100,841, is 1.

Now, the common factors can be found like this.

521:521

380:2x 2x 5x 19

100:2x 2x 5x 5

841:29x 29

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

2x 2x 5 = 20

Therefore, the value for common factors is 20.

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 = 16650118000/(1x20)

LCM = 16650118000/20

LCM = 832505900

Thus, we can understand that the LCM of 521,380,100,841 is 832505900.
