The LCM of 8,321,748,663 is 6242808.

Find LCM of 8,321,748,663 with Prime Factorization


2 8, 321, 748, 663
2 4, 321, 374, 663
3 2, 321, 187, 663
17 2, 107, 187, 221
2, 107, 11, 13

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

2 x 2 x 3 x 17 x 2 x 107 x 11 x 13 = 6242808

Therefore, the lowest common multiple of 8,321,748,663 is 6242808.

LCM Formula to Find Lowest Common Multiple of 8,321,748,663

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.

8 x 321 x 748 x 663 = 1273532832

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.

8 : 1, 2, 4, 8

321 : 1, 3, 107, 321

748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748

663 : 1, 3, 13, 17, 39, 51, 221, 663

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 8,321,748,663, is 1.

Now, the common factors can be found like this.

8:2x 2x 2

321:3x 107

748:2x 2x 11x 17

663:3x 13x 17

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 3x 17 = 204

Therefore, the value for common factors is 204.

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 = 1273532832/(1x204)

LCM = 1273532832/204

LCM = 6242808

Thus, we can understand that the LCM of 8,321,748,663 is 6242808.
