Find LCM of 813,360,798,765,460 with Prime Factorization


2 813, 360, 798, 765, 460
2 813, 180, 399, 765, 230
3 813, 90, 399, 765, 115
3 271, 30, 133, 255, 115
5 271, 10, 133, 85, 115
271, 2, 133, 17, 23

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

2 x 2 x 3 x 3 x 5 x 271 x 2 x 133 x 17 x 23 = 5073412680

Therefore, the lowest common multiple of 813,360,798,765,460 is 5073412680.

LCM Formula to Find Lowest Common Multiple of 813,360,798,765,460

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 360 x 798 x 765 x 460 = 82189285416000

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

360 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360

798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798

765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765

460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,360,798,765,460, is 1.

Now, the common factors can be found like this.

813:3x 271

360:2x 2x 2x 3x 3x 5

798:2x 3x 7x 19

765:3x 3x 5x 17

460:2x 2x 5x 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 2x 3x 3x 3x 3x 5x 5 = 16200

Therefore, the value for common factors is 16200.

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 = 82189285416000/(1x16200)

LCM = 82189285416000/16200

LCM = 5073412680

Thus, we can understand that the LCM of 813,360,798,765,460 is 5073412680.
