Given numbers are 863,988,221,869

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

The LCM of 863,988,221,869 is 12596109812.

Find LCM of 863,988,221,869 with Prime Factorization

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

13 x 863 x 76 x 17 x 869 = 12596109812

Therefore, the lowest common multiple of 863,988,221,869 is 12596109812.

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 988 x 221 x 869 = 163749427556

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

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

221 : 1, 13, 17, 221

869 : 1, 11, 79, 869

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 863,988,221,869, is 1.

Now, the common factors can be found like this.

863:863

988:2x 2x 13x 19

221:13x 17

869:11x 79

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

13 = 13

Therefore, the value for common factors is 13.

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 = 163749427556/(1x13)

LCM = 163749427556/13

LCM = 12596109812

Thus, we can understand that the LCM of 863,988,221,869 is 12596109812.
