Calculate the LCM of 813,992,268,847

Given numbers are 813,992,268,847

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

The LCM of 813,992,268,847 is 45767841504.

Find LCM of 813,992,268,847 with Prime Factorization


2 813, 992, 268, 847
2 813, 496, 134, 847
813, 248, 67, 847

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

2 x 2 x 813 x 248 x 67 x 847 = 45767841504

Therefore, the lowest common multiple of 813,992,268,847 is 45767841504.

LCM Formula to Find Lowest Common Multiple of 813,992,268,847

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.

813 x 992 x 268 x 847 = 183071366016

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.

813 : 1, 3, 271, 813

992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992

268 : 1, 2, 4, 67, 134, 268

847 : 1, 7, 11, 77, 121, 847

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,992,268,847, is 1.

Now, the common factors can be found like this.

813:3x 271

992:2x 2x 2x 2x 2x 31

268:2x 2x 67

847:7x 11x 11

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 = 183071366016/(1x4)

LCM = 183071366016/4

LCM = 45767841504

Thus, we can understand that the LCM of 813,992,268,847 is 45767841504.
