Calculate the LCM of 823,124,868

Given numbers are 823,124,868

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

The LCM of 823,124,868 is 714364.

Find LCM of 823,124,868 with Prime Factorization


2 823, 124, 868
2 823, 62, 434
31 823, 31, 217
823, 1, 7

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

2 x 2 x 31 x 823 x 1 x 7 = 714364

Therefore, the lowest common multiple of 823,124,868 is 714364.

LCM Formula to Find Lowest Common Multiple of 823,124,868

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.

823 x 124 x 868 = 88581136

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.

823 : 1, 823

124 : 1, 2, 4, 31, 62, 124

868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 823,124,868, is 1.

Now, the common factors can be found like this.

823:823

124:2x 2x 31

868:2x 2x 7x 31

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 31 = 124

Therefore, the value for common factors is 124.

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 = 88581136/(1x124)

LCM = 88581136/124

LCM = 714364

Thus, we can understand that the LCM of 823,124,868 is 714364.
