The LCM of 727,917,768,645 is 110078734080.

Find LCM of 727,917,768,645 with Prime Factorization


3 727, 917, 768, 645
727, 917, 256, 215

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

3 x 727 x 917 x 256 x 215 = 110078734080

Therefore, the lowest common multiple of 727,917,768,645 is 110078734080.

LCM Formula to Find Lowest Common Multiple of 727,917,768,645

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.

727 x 917 x 768 x 645 = 330236202240

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.

727 : 1, 727

917 : 1, 7, 131, 917

768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768

645 : 1, 3, 5, 15, 43, 129, 215, 645

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 727,917,768,645, is 1.

Now, the common factors can be found like this.

727:727

917:7x 131

768:2x 2x 2x 2x 2x 2x 2x 2x 3

645:3x 5x 43

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

3 = 3

Therefore, the value for common factors is 3.

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 = 330236202240/(1x3)

LCM = 330236202240/3

LCM = 110078734080

Thus, we can understand that the LCM of 727,917,768,645 is 110078734080.
