Calculate the LCM of 814,680,746,805

Given numbers are 814,680,746,805

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

The LCM of 814,680,746,805 is 16620268280.

Find LCM of 814,680,746,805 with Prime Factorization


2 814, 680, 746, 805
5 407, 340, 373, 805
407, 68, 373, 161

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

2 x 5 x 407 x 68 x 373 x 161 = 16620268280

Therefore, the lowest common multiple of 814,680,746,805 is 16620268280.

LCM Formula to Find Lowest Common Multiple of 814,680,746,805

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.

814 x 680 x 746 x 805 = 332405365600

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.

814 : 1, 2, 11, 22, 37, 74, 407, 814

680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680

746 : 1, 2, 373, 746

805 : 1, 5, 7, 23, 35, 115, 161, 805

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 814,680,746,805, is 1.

Now, the common factors can be found like this.

814:2x 11x 37

680:2x 2x 2x 5x 17

746:2x 373

805:5x 7x 23

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

2x 2x 5 = 20

Therefore, the value for common factors is 20.

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 = 332405365600/(1x20)

LCM = 332405365600/20

LCM = 16620268280

Thus, we can understand that the LCM of 814,680,746,805 is 16620268280.
