Calculate the LCM of 834,397,815,742

Given numbers are 834,397,815,742

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

The LCM of 834,397,815,742 is 100112446770.

Find LCM of 834,397,815,742 with Prime Factorization


2 834, 397, 815, 742
417, 397, 815, 371

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

2 x 417 x 397 x 815 x 371 = 100112446770

Therefore, the lowest common multiple of 834,397,815,742 is 100112446770.

LCM Formula to Find Lowest Common Multiple of 834,397,815,742

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.

834 x 397 x 815 x 742 = 200224893540

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.

834 : 1, 2, 3, 6, 139, 278, 417, 834

397 : 1, 397

815 : 1, 5, 163, 815

742 : 1, 2, 7, 14, 53, 106, 371, 742

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 834,397,815,742, is 1.

Now, the common factors can be found like this.

834:2x 3x 139

397:397

815:5x 163

742:2x 7x 53

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

2 = 2

Therefore, the value for common factors is 2.

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 = 200224893540/(1x2)

LCM = 200224893540/2

LCM = 100112446770

Thus, we can understand that the LCM of 834,397,815,742 is 100112446770.
