Calculate the LCM of 856,909,921,829

Given numbers are 856,909,921,829

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

The LCM of 856,909,921,829 is 198029802312.

Find LCM of 856,909,921,829 with Prime Factorization


3 856, 909, 921, 829
856, 303, 307, 829

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

3 x 856 x 303 x 307 x 829 = 198029802312

Therefore, the lowest common multiple of 856,909,921,829 is 198029802312.

LCM Formula to Find Lowest Common Multiple of 856,909,921,829

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.

856 x 909 x 921 x 829 = 594089406936

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.

856 : 1, 2, 4, 8, 107, 214, 428, 856

909 : 1, 3, 9, 101, 303, 909

921 : 1, 3, 307, 921

829 : 1, 829

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 856,909,921,829, is 1.

Now, the common factors can be found like this.

856:2x 2x 2x 107

909:3x 3x 101

921:3x 307

829:829

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

3 = 3

Therefore, the value for common factors is 3.

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 = 594089406936/(1x3)

LCM = 594089406936/3

LCM = 198029802312

Thus, we can understand that the LCM of 856,909,921,829 is 198029802312.
