Calculate the LCM of 728,887,706,873

Given numbers are 728,887,706,873

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

The LCM of 728,887,706,873 is 198995817384.

Find LCM of 728,887,706,873 with Prime Factorization


2 728, 887, 706, 873
364, 887, 353, 873

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

2 x 364 x 887 x 353 x 873 = 198995817384

Therefore, the lowest common multiple of 728,887,706,873 is 198995817384.

LCM Formula to Find Lowest Common Multiple of 728,887,706,873

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.

728 x 887 x 706 x 873 = 397991634768

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.

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

887 : 1, 887

706 : 1, 2, 353, 706

873 : 1, 3, 9, 97, 291, 873

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,887,706,873, is 1.

Now, the common factors can be found like this.

728:2x 2x 2x 7x 13

887:887

706:2x 353

873:3x 3x 97

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 = 397991634768/(1x2)

LCM = 397991634768/2

LCM = 198995817384

Thus, we can understand that the LCM of 728,887,706,873 is 198995817384.
