Calculate the LCM of 705,920,846

Given numbers are 705,920,846

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

The LCM of 705,920,846 is 389160.

Find LCM of 705,920,846 with Prime Factorization


2 705, 920, 846
3 705, 460, 423
5 235, 460, 141
47 47, 92, 141
1, 92, 3

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

2 x 3 x 5 x 47 x 1 x 92 x 3 = 389160

Therefore, the lowest common multiple of 705,920,846 is 389160.

LCM Formula to Find Lowest Common Multiple of 705,920,846

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.

705 x 920 x 846 = 548715600

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.

705 : 1, 3, 5, 15, 47, 141, 235, 705

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

846 : 1, 2, 3, 6, 9, 18, 47, 94, 141, 282, 423, 846

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 705,920,846, is 1.

Now, the common factors can be found like this.

705:3x 5x 47

920:2x 2x 2x 5x 23

846:2x 3x 3x 47

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

2x 3x 5x 47 = 1410

Therefore, the value for common factors is 1410.

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 = 548715600/(1x1410)

LCM = 548715600/1410

LCM = 389160

Thus, we can understand that the LCM of 705,920,846 is 389160.
