Calculate the LCM of 787,891,932,688

Given numbers are 787,891,932,688

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

The LCM of 787,891,932,688 is 112407889968.

Find LCM of 787,891,932,688 with Prime Factorization


2 787, 891, 932, 688
2 787, 891, 466, 344
787, 891, 233, 172

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

2 x 2 x 787 x 891 x 233 x 172 = 112407889968

Therefore, the lowest common multiple of 787,891,932,688 is 112407889968.

LCM Formula to Find Lowest Common Multiple of 787,891,932,688

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.

787 x 891 x 932 x 688 = 449631559872

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.

787 : 1, 787

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

932 : 1, 2, 4, 233, 466, 932

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 787,891,932,688, is 1.

Now, the common factors can be found like this.

787:787

891:3x 3x 3x 3x 11

932:2x 2x 233

688:2x 2x 2x 2x 43

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 449631559872/(1x4)

LCM = 449631559872/4

LCM = 112407889968

Thus, we can understand that the LCM of 787,891,932,688 is 112407889968.
