Calculate the LCM of 861,707,823

Given numbers are 861,707,823

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

The LCM of 861,707,823 is 71568903.

Find LCM of 861,707,823 with Prime Factorization


7 861, 707, 823
123, 101, 823

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

7 x 123 x 101 x 823 = 71568903

Therefore, the lowest common multiple of 861,707,823 is 71568903.

LCM Formula to Find Lowest Common Multiple of 861,707,823

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.

861 x 707 x 823 = 500982321

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.

861 : 1, 3, 7, 21, 41, 123, 287, 861

707 : 1, 7, 101, 707

823 : 1, 823

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,707,823, is 1.

Now, the common factors can be found like this.

861:3x 7x 41

707:7x 101

823:823

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

7 = 7

Therefore, the value for common factors is 7.

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 = 500982321/(1x7)

LCM = 500982321/7

LCM = 71568903

Thus, we can understand that the LCM of 861,707,823 is 71568903.
