Calculate the LCM of 820,380,898,771

Given numbers are 820,380,898,771

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

The LCM of 820,380,898,771 is 5393468820.

Find LCM of 820,380,898,771 with Prime Factorization


2 820, 380, 898, 771
2 410, 190, 449, 771
5 205, 95, 449, 771
41, 19, 449, 771

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

2 x 2 x 5 x 41 x 19 x 449 x 771 = 5393468820

Therefore, the lowest common multiple of 820,380,898,771 is 5393468820.

LCM Formula to Find Lowest Common Multiple of 820,380,898,771

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.

820 x 380 x 898 x 771 = 215738752800

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.

820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820

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

898 : 1, 2, 449, 898

771 : 1, 3, 257, 771

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 820,380,898,771, is 1.

Now, the common factors can be found like this.

820:2x 2x 5x 41

380:2x 2x 5x 19

898:2x 449

771:3x 257

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 2x 5 = 40

Therefore, the value for common factors is 40.

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 = 215738752800/(1x40)

LCM = 215738752800/40

LCM = 5393468820

Thus, we can understand that the LCM of 820,380,898,771 is 5393468820.
