Given numbers are 861,163,163,976

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

The LCM of 861,163,163,976 is 136974768.

Find LCM of 861,163,163,976 with Prime Factorization

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

163 x 861 x 1 x 1 x 976 = 136974768

Therefore, the lowest common multiple of 861,163,163,976 is 136974768.

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.

861 x 163 x 163 x 976 = 22326887184

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.

861 : 1, 3, 7, 21, 41, 123, 287, 861

163 : 1, 163

163 : 1, 163

976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,163,163,976, is 1.

Now, the common factors can be found like this.

861:3x 7x 41

163:163

163:163

976:2x 2x 2x 2x 61

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

163 = 163

Therefore, the value for common factors is 163.

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 = 22326887184/(1x163)

LCM = 22326887184/163

LCM = 136974768

Thus, we can understand that the LCM of 861,163,163,976 is 136974768.
