Calculate the LCM of 863,762,988,864

Given numbers are 863,762,988,864

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

The LCM of 863,762,988,864 is 23389730208.

Find LCM of 863,762,988,864 with Prime Factorization


2 863, 762, 988, 864
2 863, 381, 494, 432
3 863, 381, 247, 216
863, 127, 247, 72

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

2 x 2 x 3 x 863 x 127 x 247 x 72 = 23389730208

Therefore, the lowest common multiple of 863,762,988,864 is 23389730208.

LCM Formula to Find Lowest Common Multiple of 863,762,988,864

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.

863 x 762 x 988 x 864 = 561353524992

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.

863 : 1, 863

762 : 1, 2, 3, 6, 127, 254, 381, 762

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 863,762,988,864, is 1.

Now, the common factors can be found like this.

863:863

762:2x 3x 127

988:2x 2x 13x 19

864:2x 2x 2x 2x 2x 3x 3x 3

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 3 = 24

Therefore, the value for common factors is 24.

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 = 561353524992/(1x24)

LCM = 561353524992/24

LCM = 23389730208

Thus, we can understand that the LCM of 863,762,988,864 is 23389730208.
